Question

Which of the following molecules has the largest bond angle?

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

Answer 1

The correct option is C $C{O}_2$

$B{F}_3$ has a trigonal planar shape. Thus, the bond angle is ${120}^{\circ }$.
$N{H}_3$ has a lone pair and so its shape is a trigonal pyramid and thus the bond angle is ${107}^{\circ }$.
$C{O}_2$ has a linear shape since both the side atoms are the same and there are no unpaired electrons on the central atom. Thus, the bond angle is ${180}^{\circ }$.

$S{O}_2$ has a bent shape where the bond angle is around ${119}^{\circ }$.
