MCQ
From elementary molecular orbital theory we can give the electronic configuration of the singly positive nitrogen molecular ion $N_2^ + $ as
  • $\sigma {(1s)^2}{\sigma ^ * }{(1s)^2}\sigma {(2s)^2}{\sigma ^ * }{(2s)^2}\pi {(2p)^4}\sigma {(2p)^1}$
  • 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
    $\sigma {(1s)^2}{\sigma ^ * }{(1s)^2}\sigma {(2s)^2}{\sigma ^ * }{(2s)^2}\sigma {(2p)^2}\pi {(2p)^2}$
