Covalent Bonding

Question

The hybridization of N in ${NO}_{2}^{+}, {NO}_{3}^{-} {and NH}_{4}^{+}$ respectively are:

Moderate

A

$s p, s p^{2}, s p^{3}$
B

$s p, s p^{3}, s p^{2}$
C

$s p^{2}, s p, s p^{3}$
D

$s p^{3}, s p^{2}, s p$

Solution

1) ${NO}_{2}^{+}$
$H = \frac{1}{2} [V + M - charge]$
$H = \frac{1}{2} [5 + 0 - (+ 1)]$
$H = 2 (s p)$
2) ${NO}_{3}^{-}$
$H = \frac{1}{2} [V + M - charge]$
$H = \frac{1}{2} [5 + 0 - (- 1)]$
$H = 3 (s p^{2})$
3) ${NH}_{4}^{+}$
$H = \frac{1}{2} [V + M - charge]$
$H = \frac{1}{2} [5 + 4 - (+ 1)]$
$H = 4 (s p^{3})$
