Inter vs. Intra

[amar_151]

Hi. Can someone clarify what the difference between intramolecular forces and intermolecular forces is? I tend to mix these up every year I take chemistry. Are all the interactions we learned intermolecular forces?

[Kaleigh Olla 1L]

Intramolecular forces occur between atoms within a molecule. Intermolecular forces, on the other hand, occur between two separate molecules. Hope this helps!

[Jeremiah Leonor 1J]

Intra acts within a molecule; Inter acts between molecules.

[Jennifer Fuentes 2K]

ntramolecular forces are the forces that hold atoms together within a molecule. Intermolecular forces are forces that exist between molecules.

[Sristi Palimar 2E]

Intermolecular forces refer to the attractive forces that exist between molecules. An example of this would be dipole-dipole bonds. Intramolecular forces refer to the attractive forces that exist within molecules. An example of this would be a covalent bond.

I find to remember these definitions by recalling that the prefix inter- typically refers to "between two things" (ex: international = between nations) and the prefix intra- typically refers to "within something" (ex: intraregional = within a region)

[HannahArabi14a]

Hey! I found a great resource on khan academy that further breaks down inter and intra molecular forces that I highly recommend looking over and also do the practice problems afterwards.

https://www.khanacademy.org/science/cla ... lar-forces

For intramolecular forces you have to be able to remember that it means there are forces holding an atom together, for example HCl is being held together within a molecule.

For intermolecular forces it means that there are forces that exists between molecules.

Another thing that can help is distinguishing the latin root words inter and intra. Intra means within and Inter means between. So within atoms, between molecules.

Hope this helps!

[Maeve Settle 2B]

Intramolecular forces refer to the forced WITHIN molecules and between the atoms, like covalent and ionic bonds. Intermolecular forces refer to the forces BETWEEN molecules, like hydrogen bonds, dipole-dipole interactions, and LDF. Hope this helps!

[Jennifer Kainth 3L]

Hi,
The two can be easily confused. However, "inter" acts between molecules, and "intra" acts within a molecule.
Hope that helped!

[daniellediem1k]

inter = between 2 molecules, intra = between atoms in 1 molecule

[Anish_Marripati_2F]

Intramolecular forces are forces within the atom and intermolecular forces are forces between atoms

[Adithi Ayyala 2G]

A great way to remember this is the "internet", which is used by everyone, and intermolecular forces occur between all molecules. An "intranet" on the other hand, is a restricted database meant for an inner circle, and thus, intramolecular forces occur WITHIN the given species.

[Aashna Bhandari 1L]

Intermolecular forces occur between two separate molecules. For example, dipole-dipole forces and London Dispersion forces are examples of intermolecular forces. Intramolecular forces occur between atoms that are the same molecule.

[Sidharth Paparaju 3B]

Intermolecular forces occur between two separate molecules, so like hydrogen bonds and dipole attractions. Intramolecular forces, however, occur within a molecule, such as bonds.

[Mahima Manoj 1F]

They can be easy to mix up, but it helps to just remember what each prefix means. 'Inter' means between while 'intra' means within. So intermolecular forces are between molecules while intramolecular forces are within them.

[Vashe Sundar 3H]

Intramolecular forces are interactions within the molecule, while intermolecular forces are between molecules. One way I remember this is how international is referring to multiple countries, while intranational is interactions within in a singular nation.

[Denise Chavez 2G]

Intermolecular forces refers to forces that occur between molecules and intramolecular forces refers to forces that occur between atoms within a molecule.

[Aashna Sibal 2F]

Intermolecular forces are the forces that occur between different molecules. Intramolecular forces are forces that occur within a certain molecule. Intramolecular forces hold atoms together to form a molecule. Intermolecular forces hold molecules together to form solids, or liquids, etc.

[Ashley Wilson 2L]

Intermolecular forces are attractions between separate molecules, while intramolecular forces are bonds between atoms in a given molecule.

[Janice Hu 2L]

Intra = within a molecule (examples: covalent, ionic, metallic bonding)
Inter = between molecules (examples: dipole-dipole interactions, hydrogen bonding, LDFs)
"Inter" might remind you of interstate highways, which connect different states just like how intermolecular forces connect different molecules.
The "a" in "intra" could also remind you that intramolecular forces only involve a single molecule.

[Edmond Chu 1C]

ITNTRAmolecular forces occur WITHIN the molecule (like intra/inside). INTERmolecular forces occur between 2 different molecules. Hope this helps!

[Samir Panwar]

Intramolecular forces act within a single molecule, while intermolecular forces act between two different molecules.

[Lindsey Walter 3E]

Intra means that the interactions will be within the same molecule. Inter means that the interactions will be between two separate molecules.

[Jelix Tsan 2H]

Intermolecular forces refer to forces between molecules (ex: hydrogen bonding, dipole-dipole, LDF), while intramolecular forces refer to forces within a molecule that holds it together (covalent, ionic).

[Harshitha_Pandian_3F]

The way that I remember the difference between Inter and Intra is looking at highways. Interstate highways are between different states, similar to intermolecular forces that work between molecules.

[Arshaun Faraji 2H]

Inter is between molecules
intra is within the molecule

[505807269]

Intramolecular forces are the forces that hold atoms together within a molecule. Intermolecular forces are forces that exist between molecules.

[Hope Galarneau 1A]

I think what helps is to know what the meaning of intra and inter mean. Inter means between and intra means within. Thus, intermolecular is going to be between molecules while intramolecular is going to be within a molecule.

[Ananya Sridharan]

Intermolecular forces are forces in between molecules. This would include stuff like hydrogen bonds and van der wall interactions. Intramolecular forces are forces in between atoms of a molecule. So this would be ionic and covalent bonds.

[Natalie Quilala 1I]

Hi there, intermolecular forces occur between two separate molecules, while intramolecular forces occurs between atoms within the molecule itself.

[Amy Huynh 1B]

Intermolecular forces are forces that act between molecules.
- LDF, H-bonds, ion-dipole, dipole-dipole

Intramolecular forces are forces that act between the atoms of a molecule.
- covalent bonds, ionic bonds

[Sneha Anantharaman2D]

As everyone said above, intermolecular forces refer to the forces that come into play when different molecules interact, and these include LDFs, dipole-dipole, hydrogen bonding, etc. On the other hand, intramolecular forces refer to the forces acting between atoms within the same molecule, which include ionic and covalent bonding.

[Ryan Lafferty 1L]

Hi. Intermolecular forces refer to forces between separate molecules, whereas intramolecular forces refer to forces between atoms of the same molecule.

[605607825]

Hello,

Intramolecular forces (ionic bonds, covalent bonds) act within molecule whereas intermolecular forces( ion-dipole, hydrogen bonding, dipole-dipole, and London Dispersion to name a few) act between molecules! Intramolecular forces are the forces within the molecule that hold atoms together. Intramolecular forces tend to be stronger than intermolecular forces.

Here's a good diagram displaying intermolecular forces! :

I hope this was helpful!

[Sean Sanders 1E]

Intermolecular forces occur between atoms of different molecules (hydrogen bonding, London dispersion forces, dipole-dipole attractions, ion-ion interactions). Intermolecular forces occur between atoms within the same molecule (ionic bonds, covalent bonds).

[sophiavmr]

The prefix inter refers to "between 2 things" (like interstate highway= a highway that runs between states) while the prefix intra refers to "within something" (an intrastate highway= highway that runs within a state, connecting various parts of the state together)

[Rishab_Haldar_3B]

Intermolecular forces are forces that exist between molecules, whereas intramolecular forces are forces that exist between atoms within a molecule.

[Erin Woolmore 1C]

"Inter" is between molecules, and "intra" is within a molecule!

[madeleinewright]

Intermolecular forces are forces between two molecules, whereas intramolecular forces are forces within a molecule.

[Yewon Jang 3K]

Intermolecular forces are forces that occur between two molecules. intramolecular forces occur within the same molecule.

[Abigail Tran 14a]

Intra means within so intramolecular means within a molecule. Inter means in between so intermolecular means in between molecules.

[Somin Lee]

Inter molecular forces are between molecules and molecules. Breaking these forces do not affect chemical properties or characteristics of the substance since it's still the same molecule.
Intra molecular forces are between each atom of the molecule. Breaking these forces are changing the type of molecule and making it different substance.

[Minh Nguyen 3H]

Intermolecular forces occurs between separate molecules, while intramolecular forces occur between the same molecule.
An easy way I remember this is the difference between interpersonal and intrapersonal, the former preferring the company of people, and the latter type of person preferring their own company.

[Furkan Acar 3C]

Intramolecular forces are simply inside a molecule. For example, the interactions of atoms inside molecules. Intermolecular forces are between molecules. That's pretty much it. Just know the difference between intra and inter and you should be find.

[Mahli Martinez 2I]

Prefixes are so important in the physical science world. So 'intra' means within and 'inter' means between. In terms of chemistry, intra would refer to bonds within the molecule, while intra would mean bonds between molecules. I remembered this by thinking of other words that being with inter, such as international(means between nations) and intermission (a break between time intervals).

[Olivia Ghorai 1J]

The way I think of it is that intra means "within" and inter means "between". I remember it by thinking about the word "international"- because international means between nations, not within a nation. Hydrogen bonding for example, is an intermolecular force because it is a force that acts between molecules not within a molecule.

[Polo Morales 3C]

Hello! As for everything, "intra" means within and "inter" means between one and another. INTERmolecular means between one molecule and another. INTRAmolecular means within an atom. Hope this helps!

[Abigail Tran 14a]

intra means within so intramolecular is within a molecule. inter means between intermolecular is between molecules

[Abigail Tran 14a]

intra means within so intramolecular is within a molecule. inter means between intermolecular is between molecules

[Abby 2B]

hi, intramolecular forces are forces that hold atoms together within a molecule, and intermolecular forces are forces that exist between molecules.

[Amaris Cagungun 1F]

Intra acts within a molecule and inter acts between molecules

[Ginny Ghang 1B]

Intermolecular forces are the forces between the molecules. This includes dipole-dipole, ion-dipole, LDFs, and Hydrogen bonding. Intermolecular forces are weaker than intramolecular forces. Intramolecular forces are the forces within a molecule that hold the atoms. this includes ionic bonds and covalent bonds.

[Bela Patel 2B]

Intermolecular forces are forces that are between molecules, while intramolecular forces are forces that are within a molecule.

[Ayla3H]

Intramolecular forces are the forces that occur between ATOMS in a molecule.
Intermolecular forces are the forces that occur between MOLECULES.

A trick that helps me remember is that international flights are flights between different countries similar to how intermolecular forces are the forces between different molecules. Hope this helped!

[Connor_Olsen_2K]

Inter is forces between molecules. Such as H2O to another H2O. Intra refers to bonds in a molecule between atoms, such as H single bonded to the O.

[305805394]

Hi,

I think intramolecular force is the force that takes place inside a molecule usually between&among atoms. For example, a single bond between two Carbon is longer but weaker than a double bond between them. at this time, we are talking about the intramolecular force with in a molecule.

While for the other kind of force, intermolecular force, London Dispersion Force is a good example to appropriately illustrate its difference between intramolecular force. We know that every molecule exhibit a London Dispersion Force with another same molecule. In this scenario, we are talking about intermolecular force.

Hope this could address your concerns.

[Vanessa_Ong_3F]

Intermolecular forces are forces that exist between molecules, while intramolecular forces hold atoms together within a molecule.

[JohnathanH_1H]

Intermolecular forces happen between molecules such as dipole-dipole, dipole-induced-dipole, and such. Intramolecular forces happen inside the molecule such ionic or covalent bonding

[Zoe Dhalla 3I]

Intramolecular forces are the forces that hold atoms together within a molecule. Intermolecular forces are forces that exist between molecules. Intermolecular forces are categorized into dipole-dipole forces, London dispersion forces, and hydrogen bonding forces. Intramolecular forces are categorized into covalent, ionic, and metal bonds

[Zara Okeiyi 3C]

Intramolecular forces occur within the same molecule while intermolecular forces occur between two different molecules

[605720459 1I]

Intermolecular forces are between two different molecules, so these include forces such as dipole-dipole, ion-ion, dispersion forces, etc. However, intramolecular forces are the bonds that create a singular ionic compound or covalent molecule between atoms.

[Madelyn_Rios_2c]

Intramolecular forces are ones that occur within the same molecule while intermolecular forces occur between two different molecules, the best way I find to remember it is to think of an interstate highway which goes between two states like intermolecular forces work between two molecules.

[Luke Hatch 1G]

Intramolecular forces are found within a molecule. Bonds are an example of intramolecular forces (as in whether covalent, ionic, or metallic bonds form). Intermolecular forces, however, are found between molecules. These are weaker forces that effect viscosity, melting point, etc.. Hydrogen bonds are an example of intermolecular forces.

[Alexis Rempillo 3B]

Intra means 'within' and inter means 'between'. Using the prefixes, intramolecular forces would be the forces that are within the molecules, and intermolecular forces would be between the molecules. Intramolecular forces are also generally stronger than intermolecular forces.

[Daniela G 2C]

Intramolecular forces are the forces with a molecule (the forces that hold the atoms within the molecule together). Intermolecular forces are the forces between molecules. A way to remember the difference is intra means "inside/within" and inter mean "amongst/between"

[Warren Jolicoeur 1B]

Intermolecular forces are forces that occur between two molecules while intramolecular forces occur within the same molecule.

[Amy Jordan 2A]

Hi, Intermolecular forces occur between separate molecules (ex. dipole-dipole or LDFs), while Intramolecular forces occur within the atoms of a molecule or compound (ex. ionic or covalent bonds).

[Edriana J Altea 2G]

Hello! I agree with everyone above! Inter indicates something happening between two molecules while intra indicates something that is happening within something.

[Jessica Servoss 1H]

Intra = forces that hold atoms together WITHIN a molecule
Inter = forces that occur between SEPARATE molecules
Intramolecular forces are usually stronger than intermolecular forces.

[105743571]

Intermolecular forces are interactions between two separate compounds. This includes dipole-dipole interactions, London dispersion forces, and hydrogen bonding. Intramolecular forces are interactions within a molecule. This includes covalent bonding and ionic bonding.

[Darlene Luu 1H]

Intermolecular forces is the forces BETWEEEN molecules while intramolecular forces is the force WITHIN a molecule.

[Ethan Mai 1D]

Inter refers to the forces between molecules while intra refers to the forces between atoms. You can think of inter- being related to the outside of a molecule while intra- refers to the internal components of a molecule.

[Jaipal Virdi 2I]

Intra- Refers to forces between atoms within a molecule
Inter- Refers to forces between two molecules

I would recommend watching the video below as it is super helpful and goes into much more detail:
https://www.youtube.com/watch?v=Ir2SnPF7eCU

[Narin Maisha 2H]

Intramolecular forces are the forces that are between atoms holding them together in a molecule
Intermolecular forces are forces that occur between two different, nonconnected molecules

[Ayla3H]

Intra: within a molecule; between atoms
Inter: between molecules

I like to think of this as INTERnational flights refer to travel between countries --> INTERmolecular forces are between molecules.

[Violet Mbela 2B]

Intra is within itself, inter is between one or more.

[Aashna Sibal 2F]

Intramolecular forces are the forces between atoms within one molecule. For example, the bonds between H and O in water. Intermolecular forces are forces between multiple molecules of something, like multiple molecules of water.

[Ameen Shaheen 2I]

Intermolecular forces are forces between molecules while intramolecular forces are forces within a molecule amongst the atoms themselves.

[Jamie Lau 2J]

Hi, intramolecular forces happen within a molecule between its atoms while intermolecular forces happen between multiple molecules.

[SheaZenker_3F]

intramolecular forces is within the molecule between atoms
intermolecular forces are between molecules

[Claudia Longo 2J]

Hi. Can someone clarify what the difference between intramolecular forces and intermolecular forces is? I tend to mix these up every year I take chemistry. Are all the interactions we learned intermolecular forces?

You could remember the differences by thinking about what different examples of them are. For instance, examples of Intramolecular bonding are ionic and covalent bonds. Meanwhile, examples of intermolecular forces are ion-dipole, dipole-dipole, ion-ion, London dispersion forces, etc. Intramolecular forces are forces between one molecule, while intermolecular forces are between molecules!

[Ellen Brock 2I]

Intra is going to be referring to forces within an atom while inter is going to be between two different molecules. My HS teacher told us to think of it as an interstate, connection between two different states through a road. Just like a connection of two different molecules through a bond

[Hana Aflatooni]

Intra-between molecules. inter-inside the molecules

[Madelyn_Rios_2c]

intramolecular forces are within the molecule and intermolecular forces are between molecules

[Sofia Potter 1I]

Intramolecular forces are contained within an individual molecule, while intermolecular forces are between molecules. I always remember this by comparing it to other words: intramural means you're playing within the same school, and international means between nations, for example.

[eve444]

Intermolecular forces are what happens between molecules (LDF, Dipole-Dipole, Hydrogen Bonding, etc.) whereas intra molecular forces are whats happening within a molecule (covalent bonds, ionic bonds, etc.)

[Caitlin_Chheda_1K]

Intramolecular forces are the forces between two atoms/elements within the molecule itself. For example in HCl, the intramolecular force would be between the H atom and the Cl atom. Intermolecular forces are forces between multiple molecules. For example, the intermolecular forces would be between one molecule of HCl and another molecule of HCl.
