LDF vs. Van Der Waals

[Andrew Nguyen 2K]

Are London dispersion forces and van der waals forces truly the same? I oddly recall them being taught as two separate forces but they seem to be interchangeable within this course?

[Baffour Adusei 1L]

Yes, I'm pretty sure they are interchangeable names.

[azurexrose]

As far as I've learned, they've been interchangable with each other.

[Srikar_Chintala_1E]

They are the exact same thing. The names are simply interchangeable.

Ya based off what lavelle said in class it seems like it just depends on where you and varies from textbook to textbook because there is the also induced dipole-induced dipole

[ElizabethKarlin2E]

i think they're just two different names for the same thing.

[Allison Li 2F]

Yes, LDF and Van der Waal forces are the same. As professor Lavelle said in lecture, they are also referred to as induced-dipole-induced-dipole.

[Trisha Nagin]

Yes they are the same forces, the names are interchangeable.

[Jahnavi Srinivas 2H]

LDFs and Van der Waals are different names for the same forces. Induced-dipole Induced-dipole is also another term that refers to these same forces.

[SofiaMammaro-1K]

They are the same thing, but I think the most common name is LDF

[Jillian Sarquiz- 2B]

I believe they are the same force.

[Fiona H 2E]

The two terms can be used interchangeably. Both refer to a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms from temporary dipoles :)

[Amanda Dankberg 1B]

Yes they are the same thing just with different names :)

[sidneypalacios]

Yes they are the same

[Minh Nguyen 3H]

The names are interchangeable, and they refer to the same force.

[305723807]

yes

[Akshat Katoch 2K]

They are both the same thing and refer to the same force. I think that LDF is used more than Van Der Waals, but since they are the same thing it doesn't really matter how you refer to them.

[Shannon Lau 14B - 1H]

LDFs are sometimes called Van Der Waals. London dispersion forces are defined as the intermolecular forces that occur between atoms and between non polar molecules as a result of the motion of electrons while van der Waals forces are the weakest intermolecular force and consist of dipole-dipole forces and dispersion forces. They are interchangeable and are both the weakest forces.

[Abigail Tran 14a]

yes they are interchangable!

[michaelcrisera]

Yes, London Dispersion Forces, Van Der Waals, and induced dipole induced dipole are all interchangeable names for the same intermolecular force.

[Rachel Bartley 2B]

Yes, the two are the same and can be interchanged. They are the weakest intermolecular forces that can be found whenever any atom is bound to another.

[trevina_brown_2A]

Yes they are the same

[005493723]

Yes, London Dispersion Forces and Van Der Waals can be used interchangeably. They both refer to the forces that all molecules experience towards each other.

[Edriana J Altea 2G]

Yes, what everyone is saying is correct. Those terms are the same and they are interchangeable.

[William Huang 1K]

LDFs and Van Der Waals are the same thing if I recall correctly

[Jessica Servoss 1H]

I remember learning LDF as Van Der Waals in high school chemistry, but I believe they are the same thing... there's just lots of different names for this particular force :)

[Daniel Tabibian 3K]

They are the same forces. The names are interchangeable.

[Samidha Menon 1E]

London Dispersion Forces have a bunch of different names, including Van der Waals!

[eve444]

yea, they're the same thing. It's just that it has interchangeable names

[Luke Schwuchow 14A]

With these names, you can use them interchangeably since they are exactly the same thing. We have these 2 names because some scientists perfer using different names.

[Kelly_Luong_1F]

Both can be used interchangeably along with induced dipole-induced dipole to refer to the same force!

[405566265]

they're the same but VDW also includes induced dipole induced dipole etc.
