Delta molecular orbitals are formed by _________ a

If E is the total energy of the combining atomic orbitals, and E_b and E_a are the energies of the bonding and antibonding molecular orbitals formed, respectively, then

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.

According to MOT, two atomic orbitals overlap relsulting in the formation of molecular orbital. Number of atomic orbitals overlapping together is equal to the molecular orbital formed. The two atomic orbital 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. theenergy of bonding molecular orbital is less than that of the pure atomic orbital by an amount Delta . this is known as the stabilization energy. the energy of antibonding molecular orbital is increased by 'Delta' (destabilisation energy) The bond order of N_(2)^(-) is equal to that of
