Select correct about the following change

$NO_2^ +  \to N{O_2} \to NO_2^ - $

  • A
    Increase of $N-O$ bond order
  • ✓
    Decrease of $O-N-O$ bond angle
  • C
    Decrease of $N-O$ bond length
  • D
    All of the above
✓

Answer

Correct option: B.
Decrease of $O-N-O$ bond angle
b
The bond angle $NO _{2}^{+}, NO _{2},$ and $NO _{2}^{-}$ are $180^{\circ}, 134^{\circ}$ and $115^{\circ}$ respectively $NO _{2}^{+},$ and $NO _{2}^{-}$ undergoes, sp and sp $^{2}$ hybridization respectively.
