N 2 and O 2 are converted to monocations N 2 + and O 2 + respectively, which is wrong statement-

Options

  1. AIn N 2 + , the N - N bond weakens
  2. BIn O 2 + , the O - O bond order increases
  3. CIn O 2 + , the paramagnetism decreases
  4. DN 2 + becomes diamagnetic

Correct answer

D. N 2 + becomes diamagnetic

Step-by-step solution

O 2 has bond order = 2 while O 2 + has bond order 2.5 . According to MOT, N 2 ⊕ , paramagnetic and O 2 + is also paramagnetic
