Answer to Question #22869 in Inorganic Chemistry for sherrymalik

Question

molecular orbitals for N2-

Answer 1

Molecular orbital configuration for N₂ = [sigma (1s)]^2 [ sigma*(1s)]^2 [sigma (2s)]^2[sigma*(2s)]^2 [pi(2px)]^2 [pi(2py)]^2 [sigma(2pz)]^2

N₂^- ions is formed by the accept of one electron to N₂ molecule...this electron will be accepted to sigma(3s) orbital...
hence molecular orbital configuration of N₂^- = [sigma (1s)]^2 [ sigma*(1s)]^2[sigma (2s)]^2 [sigma*(2s)]^2 [pi(2px)]^2 [pi(2py)]^2 [sigma(2pz)]^2[sigma(3s)]^1
