Hi,
I would appreicate it if someone could explain why bond pair-bond pair repulsion is not greater than bond pair- lone pair repulsion?
Cheers

Lone pairs, are well, lone pairs of electrons and so do not bond with other atoms. Thus their orbitals are shorter and more round and so the electron density lies closer to the nucleus. Thus, a lone-pair bond-pair combination will have more electrostatic repulsion than a bond-pair bond-pair simply because the electron density is more spread out.

I agree, but surely the bolded bit is an oxymoron?

Ah yes, my wording is off. I was trying to mean in the sense that as a result it's more spread out, not the actual electron density itself.
