Molecular orbital theory is based on the principle of linear combination of atomic orbitals (LCAO). According to LCAO, when respective atomic orbitals of the atoms interact, they undergo constructive interference as well as destructive interference giving two type of molecular orbitals, i.e., bonding molecular orbital and antibonding molecular orbital of electrons. Electrons in these orbitals are filled according to aufbau principle, Pauli's exclusion principle and Hund rule.Which of the following is INCORRECT?Which of the following pairs have identical bond order? Among the following the INCORRECT statement
