Answer: C) 2.5 Explanation: Bond Order  = 1/2[ Nb - Na] where Nb = Number of electrons in bonding molecular orbitals. Na = Number of Electrons in antibonding molecular orbitals   Bond Order of N2⁺: Total number of electrons: 13 Electronic Configuration= :σ1s² σ*1s² σ2s² σ*2s² π 2py² [π2pz² σ2px1 ] Bond Order = [9-4]/2 = 5/2 = 2.5.
