Repulsion Strength

Postby akroberts » Sun Nov 18, 2018 7:17 pm

What do the different types of repulsion strengths (lone-lone, lone-bonding, and bonding-bonding) look like in VSEPR structures?

The different repulsion interactions are what gives molecules their shape. For example we can see how bond angles are greater between lone pairs and bonded pair electrons than between two bonded pair of electrons. This is because lone-bonded pair repulsion strength is greater than bonded-bonded pair electron repulsion.

Lone pairs of electrons cause much more repulsion, therefore when there is a lone pair present, it will "push away" the other atoms and decrease their bond angles.
