σ2PZ molecular orbitals in N2 has least energy.
Explanation:
The bonding orbital's energy is less than the antibonding orbital energy. so the energy increasing order is σ2PZ < π2py π*2Py < σ*2PZ
and the from the given σ2PZ has lowest energy and it can accept electrons and therefore it is known as electron acceptor.
N2 has four molecular orbitals of 1s and 2s. Orbitals 'p' combines to form sigma (σ) with it two pi bonds perpendicularly.
