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 $NO _{2}^{+}$.
