Repulsion Strength
Why is the electron repulsion strength stronger for lone-lone PR> lone-bonding PR> bonding-bonding PR?

Re: Repulsion Strength
Lone pairs are close to each other than any other combination of pairs. Therefore lone -lone have the greatest repulsion strength.

Re: Repulsion Strength
Lone pairs have the greatest repulsion because they are closer together. Lone bonding is the next strongest because it is the next closest. Bonding-bonding pairs are the weakest because the electrons are more spread apart since each atom takes an electron within its cloud.

Re: Repulsion Strength
Electron repulsion between electron density regions is directly proportional to the size of electron clouds. Since lone paired electrons sense attraction only from one nucleus, they typically take up a larger space and thus exert a larger repulsion force. On the other hand, bonding paired electrons sense attractions from two nucleus, and thus they take up a smaller space and generate a smaller repulsion force. Therefore, lone pairs-lone pairs > lone pairs-bonding pairs > bonding pairs-bonding pairs.
Hope this can help!

Re: Repulsion Strength
It depends on the distance between them. Since lone pairs are the closest to each other, they have the greatest repulsion strength.

Re: Repulsion Strength
Lone pairs have the greatest repulsion strength because they are the closest to eachother.
