Which of the following statement is not correct from the view point of molecular orbital theory?

According to MOT, two atomic orbitals overlap resulting in the formation of molecular orbital formed. Number of atomic orbitals overlapping together is equal to the molecule orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the 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 orbitals by an amount Delta . This known as the stabilization energy. The enerby of antibonding molecular orbital in increased by Delta' (destabilisation energy). Q. Which of the following statements is not correct regarding bonding molecular orbitals?

According to the molecular orbital theory which of the following statement is incorrect? [LUMO = lowest unoccupied molecular orbital]
