H2O Shape?

[Sophia Kangavari 1D]

Hi! I am a bit unclear on whether water (H2O) is considered tetrahedral planar or bent? Is is both? I remember professor Lavelle emphasizing that it is in fact "bent" but isn't tetrahedral planar also correct? Thanks!

[Barbara Soliman 1G]

It is bent because of the lone-pair repulsion pushing down on the molecule. So it is not tetrahedral but bent with 104.5-degree angle. Hope this helps!

[Ayla3H]

The shape of H2O is bent, or, angular. This is due to VSEPR model stating that lone pair electrons have greater repulsion than bonding electrons and therefore both of the lone pairs on Oxygen atom repel each other and the bonding pairs with a great force, forcing the molecule to assume a "bent" shape.

[Konmal Ali 1G]

Bent molecules have two bonds and one lone pair. Furthermore, tetrahedral geometry occurs at 109 degrees, but for H2O it is about 104.5 degrees. As a result, H2O is bent.

[Matt Vargo 2D]

H2O has a bent shape. This is because the lone pairs repel each other, thus creating its bent/angular shape. Whereas the expected bond angle in a tetrahedral molecule is 109.5°, the bond angle for H2O is only 104.5°. This bond angle exhibits H2O's bent shape.

[Jessica Li 1G]

H2O is bent due to the 2 lone pairs on the Oxygen atom that causes electron repulsion forces. These repulsion forces push down on the bond angle of the molecule and cause it to have a 104.5 degree bond angle. Tetrahedral has a 109.5 degree bond angle so H2O cannot be tetrahedral planar.

[Maxwell Yao]

Hi,

H20 is bent because oxygen has two lone pairs in addition to the two bonds it forms with hydrogen. Because the repulsion between the lone pairs is so strong, the shape of H2O is bent.

It's easy to visualize after you draw out the structure because you can then see the two regions of electron density that result from the lone pairs.

Hope this helps.

[Emily Wan 1l]

Water has two lone pairs of electrons on the oxygen, which exit repulsion upon each other as they are both negatively-charged. This causes the molecular shape of water to be bent, with an angle (104.5) slightly lower than that of the tetrahedral shape.

[Kathryn Heinemeier 3H]

it is only bent not tetrahedral because of the repulsion from the lone pair

[tristenleem3B]

H2O is bent shape because of the higher electronegativity of the oxygen model and the 2 lone pairs of the electrons on the O molecule.

[Michelle Jeong 1B]

Hi, h20 has a bent shape because of its lone pairs. So unlike a tetrahedral, the bond angles are less then 109.

[Yajing Feng 2J]

Hi!

H2O is bent shape and not tetrahedral because the VSEPR model looks at shape with the bonding atoms and not lone pairs in the sense that H2O can't be tetrahedral since there's only two atoms bonded to the central atom whereas the tetrahedral shape requires four atoms to be bonded to the central atom. The H2O shape is bent because of the lone pair of electrons repelling the bonding pairs since the repulsion ranks as follows: lone-lone > lone-bonding > bonding-bonding. This means that lone pairs are strong enough to repel the bonding pairs so that H2o results in the bent shape.

Hope this helps.

[Elizabeth Kim 2K]

Hi! H2O has a bent shape because of the two lone pairs on the O atom. Lone pair electrons have greater repulsion than bonding electrons, so the bond angles for H2O are 104.5, which are slightly lower than the corresponding bond angles for a tetrahedral shape, 109.5. Hope this helps!

[105743571]

The molecular geometry of H20 is tetrahedral because it has 4 electron domains. Its electron geometry is bent.

[Jennifer Kainth 3L]

Because of its lone pairs, H2O has a bent form.
Also, the binding angles are smaller than 109, unlike a tetrahedral.

[Emily Hou 1H]

The arrangement of the electron regions is described to be tetrahedral, but the actual molecular geometry is bent since only actual bonding atoms are considered when naming molecular geometry.

[Hailey Sarmiento 3E]

hi! H2O has a tetrahedral electron domain geometry, but its molecular geometry (which excludes electrons when naming) is bent.

[Matthew Vu 3C]

H2O has a molecular geometry of bent, but its electron density is tetrahedral.

[Jamie Lau 2J]

H2O's shape is bent. H2O's lone pair electrons have greater repulsion than bonding electrons, which results in the bond angles being less than that of a tetrahedral.

[Triston Dinh 1D]

The electron pair arrangement of H20 would be tetrahedral since it has a total of 4 regions of electron density (2 lone pairs and 2 bonding atoms). However, its molecular shape is bent. The two lone pairs cause repulsions that affect the positioning of the two hydrogen atoms and thus cause its bent molecular geometry under the tetrahedral electron pair geometry.

[Cory Poon 3G]

H20 is considered bent! It has a specific angle that can be written for it, but in general, all bend/angular molecules like water can be written as <120 degrees.

[Victoria Sigala 2A]

Hi, H2O would be just bent and not tetrahedral. The lone pairs creates this bent shape resulting in a bond angle of 104.5 and not 109.5 like the bond angels for a tetrahedral.

[AndreyCastellanos 3H]

It is bent because of the lone-pair repulsion pushing down on the molecule. So it is not tetrahedral but bent with 104.5-degree angle

[Om Patel]

the shape is bent because the central atom has lone pair, which causes repulsion, making it bent

[Anubhav_Chandla1G]

Due to the 2 pairs of lone pairs on the H atom and the compound being a polar compound, the H20 compound leads to a bent shape. This creates a bent structure with a bond angle of 104.5 degrees.

[haryn Shin 1H]

According to VSEPR, the molecular geometry of H20 is Angular or bent, because the central atom O has lone pairs. Hope this helps!

[Lindsey Walter 3E]

H20 will have a bent shape. This is because oxygen has 2 bonds and 2 lone pairs. The repulsion between the lone pairs is the strongest repulsive force dictating molecular shape, making the shape bent.

[Anthony_Rio_3K]

The electron geometry of H2O is bent because electron geometry considers lone pairs, whereas molecular geometry doesn't not, so the molecular geometry of H2O would be tetrahedral.

[Benjamin Nguyen 1J]

H2O is bent because it has two bonded atoms and two lone pairs. Molecules that are AX2E2 are bent.

[Shreya Arcot 3K]

H2O has a bent shape.

When drawing the Lewis Structure of H2O, it has 4 bonding regions (tetrahedral geometry), 2 of which are lone pairs. These lone pairs produce a bent shape.

[Akshat Katoch 2K]

H2O has a bent shape. It has two lone pairs that push down making the bond angle 104.5. Tetrahedral planar has a bond angle of 109.5 so H2O could not be tetrahedral planar.

[Abigail Tran 14a]

h2o has two bonds and one lone pair so it is bent

[Lawrence Javelo Disc 3B]

H2O is considered bent. The reason for this is because it has 3 atoms, one center and 2 connected and a lone pair that "pushes" or repulses the other atoms away. Based on both of these things, we can state that this molecule is bent. To be tetrahedral, there would have to be a total of 5 molecules, 4 connected and 1 center.

[Anubhav_Chandla1G]

Due to the two lone pairs on the central Oxygen atom, the electron-electron repulsion causes the whole structure to take a bent shape. Tetrahedral planar would mean that there is no electron-electron repulsion pushing the hydrogen atoms down, leading to the planar shape.

[N Kanuri 2E]

H₂O has a tetrahedral electron geometry, but a bent shape. It cannot have a tetrahedral planar electron geometry because electron-electron repulsion keeps the lone pairs on oxygen as far away from each other as possible, and this happens in a tetrahedral geometry.

[Litsa Dimit 1D]

H2O is bent because it has AXE2 and the bond angle is 104.5!

[Yewon Jang 3K]

H2O has 4 regions of electron density so its electron geometry is tetrahedral but its molecular shape is bent since there are only 2 atoms actually bonded to the central atom.

[michaelcrisera]

The molecular geometry of the H2O molecule is bent according to the VSEPR model. This is because it has 2 lone pairs and 2 bound pairs of electrons, so the greater electron electron repulsion of the lone pairs causes the two bound pairs to orient themselves in a bent shape. The electron geometry of the molecule is tetrahedral, and this is simply because the central oxygen molecule has 4 areas of electron density around it.

[Ashley Tonthat 2B]

Hello,

H2O has a bent molecular shape, but its electron arrangement is considered tetrahedral because it has 4 electron domains (2 lone pairs on the O and it is bonded to 2 H atoms). Hope this helps.

[Amy Huynh 1B]

The shape of an H2O molecule is bent. There are four regions of electron density. However, two of those regions are lone pairs while the other two are bonded pairs. The lone pairs exert a greater repulsive force than that of bonded electrons, which is why we see that molecular geometry is "bent".

[Mia Orr 3B]

We base the naming of molecular shape only on the bonded atoms, so the shape of H20 is bent/angular.

[Mason_Hoppe_1A]

Like others mentioned, the naming of the molecular structure is solely based on the arrangement of atoms. That is why the molecular structure is bent, but it is also important to note that the arrangement of the high electron density areas is tetrahedral (not square planar).

[Amaris Cagungun 1F]

The shape of an H2O molecule is bent because it has two bonded atoms and 2 lone pairs. The repulsion from the lone pairs causes it to have 104.5 degree bond angle, which is slightly lower than a tetrahedral shape (109.5 degrees).

[Isabelle Rieke-Wey 2G]

Hi!
the H2O molecule is bent, because it is a polar molecule, meaning the dipoles do not cancel out. This is due to the lone pairs on the oxygen atom, which causes for repulsion, making the bent shape. It is not tetrahedral, because the it has 104.5 degree bond angles.

[Ainsley DeMuth 1H]

The molecular shape of H2O is going to be considered bent due to the mix of lone pairs and bonds. There is technically four regions of electron density (2 bonds and 2 lone pairs) which is where tetrahedral comes into play, but the molecular shape will still be bent due to the presence of the lone pairs.

[Madison Kiggins 1E]

H2O is bent because it has 2 bonds and 2 lone pairs. The electron-electron repulsion will result in a bent shape with angles that are smaller than the original angles of the tetrahedral shape, 109.5. It will instead have angles of 104.5.

[Rachel Bartley 2B]

H2O's molecular geometry is bent because it has two bound atoms and two lone pairs on oxygen, the central atom. The two lone pairs on the oxygen atom push the two hydrogen atoms down further away from the oxygen atom and closer to each other, creating a bent shape and 104.5 degrees angle between the two H atoms.

[Chris Van 2J]

H2O would be a bent shape as the lone pairs on the oxygen would push the hydrogens making it a bent shape with 104.5 degrees bond angles!

[daniellediem1k]

H2O is bent.

[14b_student 2E]

It is bent and not tetrahedral because of the repulsion from the lone pair

[Brenda Tran 3C]

H2O has a bent shape because there are two bonds and a lone pair that changes the molecular shape from linear to bent because of the electron repulsion.

[Jessica Servoss 1H]

Water's geometric shape is bent due to the two attached atoms and the two lone pairs on the oxygen.

[405479701]

Due to the 2 lone pairs on the oxygen atom, H20 is bent.

[Sarthika Chimmula 3H]

Water is bent because the O central atom has 2 bonding pairs and 2 lone pairs.

[Natalie Quilala 1I]

H20/water is bent, as it has an AX2E2 geometry. This means it has two lone pairs and two bonding pairs. The lone pairs repel each other and the bonded atoms, resulting in the bent molecular geometry.

[Connor_Olsen_2K]

It has to be bent as it has only two bond sites with two lone pairs. In a tetrahedral, there is four bond sites.

[Harrington Bubb3A]

that makes sense so if a molecule has two lone pairs will it always be bent or is that just the case of molecules with 1 central atom and two on the side?

[Nathalia Garibay 1D]

Hello,
H2O is bent and because of it has bond angles of 104.5. It cannot be tetrahedral because the bond angle for tetrahedral is 109.5.

[Srikar_Chintala_1E]

H2O has a bent molecular shape but a tetrahedral electron arrangement.

[Katherine Li 1A]

The electronic shape is tetrahedral, as there are two lone pairs in addition to the two bonds. However, the molecular shape is bent. It's important to know the electronic shape to determine the angles of the molecular shape.

[Jiayin Yola Yan 1G]

H2O has two lone pairs and can be written as AX2E2, and thus is bent/angular.

[Miranda Hess 3I]

It's bent because 2 lone pairs + 2 bonds off of the central atom = bent. It's important to make a lewis structure to see what's up.

[Jaipal Virdi 2I]

According to the VSEPR theory, it would be bent due to the fact it has two bonds and two sets of lone pairs!

[Colby Irvine 2A]

The electron arrangement of H2O is tetrahedral, but because it has two lone pairs on the central O atom, the molecular shape would be bent. AX2E2 is the notation.

[Mahima Manoj 1F]

Since one of the regions of electron density is a lone pair, it would be bent.

[Matthew Nguyen 3G]

H2O is a bent as H--O--H there is a lone pair on O which means there's repulsion making it a 104.5 angle or bent shape.

[Benicio Rivera 1F]

The electronic geometry gives water a tetrahedral shape. The molecular geometry gives water a bent shape. Since it has 4 regions of electron density it has the electron geometry of tetrahedral. The molecular geometry is bent though, this is due to the two lone pairs repelling the bonds downward.

[Ethan Mai 1D]

The four electron groups surrounding O makes the electron arrangement a tetrahedral shape. By making two of those regions of electron density lone pairs, the shape comes out bent.

[oliviahelou]

It is bent because of the lone pair of electrons on the oxygen atom.

[Ameen Shaheen 2I]

The shape is bent due to the lone pair of electrons on the oxygen atom on the H2O molecule.

[Trisha Nagin]

The shape is bent because of the lone pair repulsion.

[Madeline_Miller]

Hi! H20 is bent because it has four regions of electron density and 2 lone pairs.

[Alyssa H]

H2O is bent/angular because the oxygen has two lone pairs, meaning there are four regions of electron density, but two bonded atoms.

[Madeline_Miller]

H20 is bent/angular because it has 4 regions of electron density and 2 lone pairs.

[205819952]

H2O has a bent shape.

[Quinn W 2A]

It has a bent shape because it only has two atoms attached to central atoms. But it does have four fields of electron densities due to the two lone pairs.

[Raizel Ferrer 1H]

H2O has the molecular shape bent because it has two lone pairs, but the electron arrangement is a tetrahedral.

[Arpita Padhy 3E]

Since it has 4 regions of electron density and 2 lone pairs, it would be considered bent/angular :)

[Hannah Choi 1K]

H2O has a bent shape because it has two lone pairs that press down on the O-H bonds. Keep in mind that lone pair-lone pair repulsion is the strongest kind of electron repulsion, followed by lone pair-bond pair repulsion, followed by bond pair-bond pair repulsion. Because lone pair-bond pair repulsion is stronger than bond pair-bond-pair repulsion, the lone pairs from the oxygen in H2O will press down on the O-H bonds, resulting in the bent shape of the water molecule.

[PatrickV]

It is considered bent because of the lone pairs. Having lone pairs doesn't make it tetrahedral, it would be tetrahedral if the lone pairs were instead bonds connected to other atoms.

[Ryan Lafferty 1L]

H2O is bent, as there are four regions of electron density, two of which are bonds and two of which are lone pairs on the central atom.

[Ashrita Singh 2F]

H2O is bent due to its lone pairs.

[305805394]

Hi,

After you draw the Lewis structure of H2O, you would notice that there are two long pairs and two single bonds connected to the central atom, Oxygen.

Therefore, the electron density surrounding oxygen is 4. And since it possesses 2 long pairs and 2 bonding pairs, is has a AX2E2 bent molecular shape.

Hope this could address your concerns.

[Kristen Bansil 1G]

The molecular geometry of H2O is angular/bent, this is due to its three regions of electron density (one region being the lone pairs). As a result, it has an angle of 104.5 degrees.

[Kristen Bansil 1G]

[Mahli Martinez 2I]

H2O has a bent shape, which can be attributed to the lone pairs on oxygen that repel each other.

[305670352]

Its bent: It has two bonding pairs and two bonding pairs. AX2E2 = bent/angular

[Polo Morales 3C]

It is bent due to the two lone pairs left on the oxygen. These lone pairs exert a great repulsive force and thus create a bent shape in the molecule of H2O.

[JafarriNocentelli 1G]

H2O is bent because there is a lone pair present on the central O atom
