Q. Which of the following statement is not correct from the view point of molecular orbital theory?
- Be2 is not a stable molecule
- He2 is not a stable but He2+ is expected to exist
- Bond strength of N2 is maximum amongst the homonuclear diatomic molecules belonging to the second period
D. The order of energies of molecular orbitals in N2 molecule is 2s < *2s < 2pz < ( 2px= 2py) < ( *2px= *2py) < *2pz
Answer: The order of energies of molecular orbitals in N2 molecule is 2s < *2s < 2pz < ( 2px= 2py) < ( *2px= *2py)*2pz
