Bent - Lone Pairs

Postby Dayna Pham 1I » Thu Nov 22, 2018 4:22 am

For the bent shape, does this include instances where there's one lone pair, as well as instances including two lone pairs?

Thank you!

Yes, the molecular shape for an AX2E and AX2E2 molecule are both bent. However, the electron geometry would be different for both.

Yes, for example, NO2 and O3 both have one lone pair and have bent molecular shape.

Adding on, if there were two lone pairs, then the angles between the atoms would be smaller than if there were only one lone pair even if they were both bent shape.

Are the angles the same or different whether it is one lone pair or two lone pairs in the bent shape?
edit - oops just saw the post above...

I presume the bond angles will be different depending on how many lone pairs there are in a bent shape. For sure they are both less than 109.5 degrees, but the more lone pairs there are the smaller the bond angle.

Bond angles will be different because the repulsion between the pairs where there is one versus two lone pairs is significant enough to have an effect on the bond angles.

Yes, the molecular geometry for both would be bent. However, they would have different electron geometries.
