H2O Shape?
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!

Re: H2O Shape?
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!
Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

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.

Re: H2O Shape?
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.

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

Re: H2O Shape?
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.

Re: H2O Shape?
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.

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.

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.

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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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.

Re: H2O Shape?
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".

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).

Re: H2O Shape?
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.

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.

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.

Re: H2O Shape?
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.
Re: H2O Shape?
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.

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.
