MCQ
${N_2}$ and ${O_2}$ are converted into monocations $N_2^ + $ and $O_2^ + $ respectively. Which is wrong
  • A
    In ${N_2},$ the $N - N$bond weakens
  • B
    In ${O_2},$ the $O - O$ bond order increases
  • C
    In ${O_2},$ paramagnetism decreases
  • ✓
    $N_2^ + $ becomes diamagnetic
✓

Answer

Correct option: D.
$N_2^ + $ becomes diamagnetic
(d)$N_2^ + $ has one unpaired electron so it would be paramagnetic.
