Q.
Which of the following correct trends of bond energy is possible to explain by the following statement?
'Successive filling of antibonding orbital reduce the bond energy between two atoms'
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
Δ
. This known as the stabilization energy. The energy of antibonding molecular orbital is increased by
Δ
′
(destabilization energy).
