Bent

[Michael Du 1E]

From class, a bent example was shown through 2 lone pairs and 2 bound atoms of a central atom. Can a bent also occur from one lone pair and 2 bound atoms? if so, would the bond angle be the same or different?

[Anish Patel 4B]

Yes, 2 bonding atoms and 1 lone pair is also a bent shape. Since there are two lone pairs in the first example, this molecule's atoms experience more repulsion and are pushed closer together which decreases the bond angle in comparison to a bent molecule with only one lone pair.

Two bound atoms and one lone pair also results in a bent structure. Its bond angle would be greater than the structure with two lone pairs since the lone pairs emit greater repulsion strength.

[Erik Buetow 1F]

Yes, this would still be a bent structure however, the bond angles would be greater since there is less repulsion from the one lone pair as opposed to there being two lone pairs involved.
