Lone Pairs vs. Bonding Pairs

Postby Ava Harvey 2B » Sat Nov 25, 2017 1:31 pm

Can someone please explain to me a little more in depth the reasoning behind why lone pairs have greater repelling effect than that of bonding electrons? I was a little confused on this concept. Thanks so much!

Lone electrons take up more space so it has greater repulsion

A possible reason why is that because a bonding pair is held in place by two atoms, its electron cloud can not spread over as large of a volume as a lone pair can. (Textbook pg.21)

In addition to the lone pair occupying a greater volume, a bonding pair is part of a sigma bond, placing it further away from the central atom whereas the negatively charged lone pair is pulled in close by the positively charged central atom, creating more repulsion power.

This is because bonded electrons are bound to a certain region of the sigma bond, whereas lone pairs are much more free to move and have more space since they aren't involved in any bonds that restrict their movement.

Bonding pairs are held in place by two atoms unlike lone pairs, so lone pairs are able to take up a larger space.

Lone pairs take up more space that bonding pairs, which leads them to have greater repulsion.
