Consider the molecules CH_4, NH_3 and H_2 O. Which of the given statements is false?

The $\displaystyle \mathrm{H}-\mathrm{C}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{CH}_4$ is larger than the $\displaystyle \mathrm{H}-\mathrm{N}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{NH}_3$.

The $\displaystyle \mathrm{H}-\mathrm{C}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{CH}_4$, the $\displaystyle \mathrm{H}-\mathrm{N}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{NH}_3$, and the $\displaystyle \mathrm{H}-\mathrm{O}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{H}_2 \mathrm{O}$ are all greater than $\displaystyle 90^{\circ}$.

The $\displaystyle \mathrm{H}-\mathrm{O}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{H}_2 \mathrm{O}$ is larger than the $\displaystyle \mathrm{H}-\mathrm{C}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{CH}_4$.

The $\displaystyle \mathrm{H}-\mathrm{O}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{H}_2 \mathrm{O}$ is smaller than the $\displaystyle \mathrm{H}-\mathrm{N}-\mathrm{H}$ bond angle in $\displaystyle \mathrm{NH}_3$.
