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 are formed by subtraction of wave-functions of atomic orbitals of same phase
Statement (C) : Non-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.
