Answer
1. VBT was theorized by W.Heitler and F.London, while MOT was proposed by F. Hund and R.S. Mulliken
2. Both of them explain the formation of compounds or molecules. VBT involves the electrons forming a bond, while MOT involves the combination of atomic orbitals to form molecular orbitals.
3. It is assumed that electrons are localized in VBT, but delocalized in MOT.
4. The paramagnetic character of oxygen is well explained by MOT, but not VBT.
