From elementary molecular orbital theory we can give the electronic configuration of the singly positive nitrogen molecular ion \[N_{2}^{+}\] as                                        [UPSEAT 2003]

A)                 \[\sigma {{(1s)}^{2}}{{\sigma }^{*}}{{(1s)}^{2}}\sigma {{(2s)}^{2}}{{\sigma }^{*}}{{(2s)}^{2}}\pi {{(2p)}^{4}}\sigma {{(2p)}^{1}}\]

B)                         \[\sigma {{(1s)}^{2}}{{\sigma }^{*}}{{(1s)}^{2}}\sigma {{(2s)}^{2}}{{\sigma }^{*}}{{(2s)}^{2}}\sigma {{(2p)}^{1}}\pi {{(2p)}^{3}}\]

C)                 \[\sigma {{(1s)}^{2}}{{\sigma }^{*}}{{(1s)}^{2}}\sigma {{(2s)}^{2}}{{\sigma }^{*}}{{(2p)}^{2}}\pi {{(2p)}^{4}}\]

D)                 \[\sigma {{(1s)}^{2}}{{\sigma }^{*}}{{(1s)}^{2}}\sigma {{(2s)}^{2}}{{\sigma }^{*}}{{(2s)}^{2}}\sigma {{(2p)}^{2}}\pi {{(2p)}^{2}}\]
