Lone pairs versus bonding pairs

Postby Gurshaan Nagra 2F » Sun Nov 12, 2017 10:43 pm

What makes lone pair electrons have a different effect on the shape of the molecule versus if it was just another bonding pair?

lone pairs and bonding pairs both effect the shape of the molecule but there is stronger repulsion between lone pairs and other bonding pairs than bonding pairs and other bonding pairs

Lone pairs have more repulsion than bonding pairs, meaning they push other electrons away more than a bonding pair would. This bends the shape of the molecule away from the lone pair.

I believe it is due to the shape of lone pairs vs. bonding pairs. Bonding pairs are electrons that are between two atoms so the electrons are farther from the atom but more localized. Lone pair electrons however are pulled closer to the nucleus of the atom since the opposing negative charge from the electron and positive charge of nucleus but since it is pulled closer the repulsion between the two electrons are stronger creating a larger degree of influence. So ultimately the electrons in a lone pair influence the shape of the molecule more than the localized bonding pairs. I hope this helps in some way.
