MCQ
$'O-N-O'$ bond angle is maximum in ?
A
$N_2O$
✓
$NO_2^ + $
C
$NO_2^ - $
D
$NO_3^ - $
✓
Answer
Correct option: B.
$NO_2^ + $
b The ONO angle is maximum in $NO _{2}^{+}$ In $NO _{3}^{-}$, bond angle is $=120^{\circ}$ due to sp $^{2}$ -hybridization with no lone pair $N O _{2}^{+}, N O _{2}^{-}$ and $NO _{2}$ have bond angles nearly $180^{\circ}( sp )$ with one lone pair, $115^{\circ}\left( sp ^{2}\right)$ with one lone pair and $134^{\circ}$ respectively.
Thus, ON O angle is maximum in $NO _{2}^{+}$.
