Repulsion Strength

Postby Max Hayama 4K » Thu Nov 15, 2018 11:01 am

Why is it that lone pair repulsion is greater than bonding pair repulsion?

This is because the two electrons in the lone pair are held closer together to the single atom compared to a bonding pair which is split between two atoms. Since the lone pair is closer to the central atom they will have more repulsion

A lone pair is also more delocalized than a bonding pair, so it will have greater ability to move around and repel other electrons.
