Question

Which has the least bond angle

• A. $Be{F}_2$
• B. $C{H}_4$
• C. $H_{2}O$
• D. $N{H}_3$

Answer 1

The correct option is C

$H_{2}O$

Due to $l_p-l_p$ repulsions, bond angle in $H_{2}O$ is lower $\left({104}^o{.5}^o\right)$ than that in $N{H}_3\left({107}^o\right)$ and $C{H}_4\left({109}^{o}28\text{'}\right).Be{F}_2$ on the other hand, has sp-hybridization and hence has a bond angle of ${180}^o$.
