Question

Which one of the following compounds has the smallest bond angle in its molecule ?

• A. $S{O}_2$
• B. $O{H}_2$
• C. $S{H}_2$
• D. $N{H}_3$

Answer 1

Answer: (C)

Molecule	Hybridi-sation	Repulsion	Bond angle
$S{O}_2$	$s{p}^2$	$lp-bp,bp-bp$	$119^{\circ }$
$O{H}_2$	$s{p}^3$	$lp-lp,bp-lp-bp-bp$	$104.5^{\circ }$
$S{H}_2$	$s{p}^3$	$-do-$	$90^{\circ }$
$N{H}_3$	$s{p}^3$	$lp-bp,bp,-bp$	$107^{\circ }$
