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

Q. According to MOT (Molecular Orbital Theory), the molecular orbitals are formed by mixing of atomic orbitals through LCAO (linear combination of atomic orbitals). The correct statement (s) about molecular orbitals is/are Statement (a) : bonding molecular orbitals are formed by addition of wave-functions of atomic orbitals of same phase Statement (b) : anti-bonding molecular orbitals do not take part in bond formation because they belong to inner shells Statement (d) : anti-bonding molecular orbitals provide stability to molecules while bonding molecular orbitals make the molecules unstable.
