Lone pairs and bonding

Postby AlyssaBei_1F » Mon Nov 19, 2018 2:49 pm

Can someone explain why larger lone pairs electrons force bonding electrons closer together?

Lone pairs are 2 electrons in one orbital and exert the largest repulsive forces, pushing bonding pairs closer together.

Lone pairs on bonding pairs have a larger repulsive force that bonding pairs or bonding pairs, so the lone pairs will push bonding pairs closer together for the molecule to reach its lowest energy state.

Because lone pairs are unbound electrons, they have a much larger electron cloud and repulsion energy, thus push down the other electron densities such as the bond angles. In class lavelle showed us that by replacing a molecule (taking it off the stick), the area becomes much more occupied and results in the surrounding bond angles to be pushed away

Lone pairs give off repulsive forces, so they push the bond pairs closer together, making the bond angles smaller.
