Step-by-step solution
According to Molecular Orbital Theory: Sigma ( ) molecular orbitals are symmetrical around the internuclear axis. Pi ( ) molecular orbitals are not symmetrical around the internuclear axis and have zero electron density along the internuclear axis. Bonding molecular orbitals are formed by the constructive interference (addition) of electron wave functions ( _A + _B ). Antibonding molecular orbitals are formed by the destructive interference (subtraction) of electron wave functions ( _A - _B ) and possess a nodal pl
