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

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

Re: Lone pairs and bonding
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.

Re: Lone pairs and bonding
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

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