Covalent Bonding and Orbital Overlap

Disadvantages of VSEPR theory

  1. Does not explain why a bond forms.
  2. Does not tell which orbitals are involved in bonding?
Hence, the need of Valence Bond Theory where "Bonds form when orbitals on atoms overlap".

Example: Overalp of orbitals explains the mechanism of bond formation
