Lone Pairs
I think I missed the lecture that this was covered, but how do lone pair electrons affect bond angles? Thanks!!:-)

Re: Lone Pairs
Bond angle is affected by the presence of a lone pair of electrons at the central atom. A lone pair of electrons at the central atom will always try to repel the bonded pair of electrons(Also called the lone pair repulsion). Therefore, the bonds are displaced slightly inside resulting in a decrease of the bond angle.

Re: Lone Pairs
An example would be AX3 and AX2E1
Both have 3 regions of electron density, however one has a lone pair (E1) which means that the bond angles here will be smaller
