Lone Pair Repulsion

Postby Chloe Blume 1F » Sun Nov 19, 2017 11:32 am

Why do lone pairs have higher repulsion in a VSPER model?

Electrons are less stable in long pairs and thus have higher energy. Higher energy causes higher repulsion.

An electron cloud of a lone pair can take up more space than an electron cloud of a bonding pair because it's less restrained because it's held in place by only 1 atom, not 2. This leads to greater repulsion.
