Q. The bond angle in ammonia molecule is
A) $90{^\circ}3'$
B) $91{^\circ}8'$
C) $106{^\circ}45'$
D) $109{^\circ}28'$
Explanation
(c)
In $NH_{3},sp^{3}$-hybridization is present but bond angle is $106{^\circ}45'$ because nitrogen has lone pair of electrons, according to VSEPR theory due to $bp$- and $lp$ repulsion, bond angle decreases from $109{^\circ}28'\$to$\ 106{^\circ}45'$
