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 ∆. This known as the stabilization energy. The energy of antibonding molecular orbital is increased by ∆‘ (destabilisation energy).
Which of the following statements is not correct regarding bonding molecular orbitals ?
- Bonding molecular orbitals possess less energy than the atomic orbitals from which they are formed
- Bonding molecular orbitals have high electron density between the two nuclei
- Electron in bonding molecular orbitals contributes to the attraction between atoms
- They are formed when the lobes of the combining atomic orbitals have the same sign
Answer
(B) Bonding molecular orbitals have high electron density between the two nuclei
