Which one of the following does not exhibit paramagnetism?

Options

  1. ANO
  2. BN O 2
  3. CC I O 2
  4. DC I O 2 -

Correct answer

D. C I O 2 -

Step-by-step solution

NO, N O 2 and C l O 2 all have odd number of electrons and therefore are expected to paramagnetic. C l O 2 - have even number of electrons ( 17 + 35 = 52 ) , so it may be diamagnetic.
