Answer #1

repulsion among different pairs

Lone-pair versus lone-pair repulsion > lone-pair versus bonding-pair repulsion

   > bonding-pair versus bonding-pair repulsion

explanation:
Electrons in a bond are held by the attractive forces exerted by the nuclei of the two bonded atoms. These electrons have less “spatial distribution” than lone pairs; that is, they take up less space than lone pair electrons, which are associated with only one particular atom. Because lone-pair electrons in a molecule occupy more space, they experience greater repulsion from neighboring lone pairs and bonding pairs.

Why is the valence shell electron pair repulsion model used to predict molecular geometry? Lone pair repulsion is stronger than bonding pair repulsion. Valence electrons are constantly moving. Lewis structures of molecules can tell the bond strength between atoms. Lone pair electrons of the central atom are attracted to the bonding pair electrons.
