Solution

The correct option is C Stabilization energy
When 2 atomic orbitals overlap, constructive overlap gives molecular orbital which are lower in energy due to interactions between atomic orbitals or it can be said that newly formed atomic orbitals are stabilised. So, the amount of energy they are lower by atomic orbitals is called stabilisation energy.

Q. According to MOT, two atomic orbitals overlap resulting in the formation of molecular orbitals. Number of atomic orbitals overlapping together is equal to the molecular orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the same phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. The energy of bonding molecular orbital is lower than that of the pure atomic orbital by an amount
