Which of the following statement is not correct from the molecular orbital theory?
- Be2 is not a stable molecule.
- He2 is not stable but He2+ is expected to exist.
- Bond strength of N2 is maximum amongst the homonuclear diatomic molecules belonging to the second period.
- The order of energies of molecular orbitals in N2 molecule is,
s2s < s* 2s < s2pz < (p2px = p2py) < (p*2px = p*2py) < s* 2pz
Answer
(D) The order of energies of molecular orbitals in N 2 molecule is, s 2 s s * 2 s s 2 p z p 2 p x = p 2 p y ) p *2 p x = p *2 p y ) s * 2 p z
