Q. Correct order of bond angles in $NH_{3}$, $PCl_{3}$ and $BCl_{3}$ is
A) $PCl_{3} > NH_{3} > BCl_{3}$
B) $NH_{3} > BCl_{3} > PCl_{3}$
C) $NH_{3} > PCl_{3} > BCl_{3}$
D) $BCl_{3} > NH_{3} > PCl_{3}$
Explanation
(d)
Compound Bond angle
$NH_{3}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 107{^\circ}$
$PCl_{3}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 93{^\circ}$
${BCl}_{3}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 120{^\circ}$
