Consider the molecules \( \mathrm{CH}_{4} \), \( \mathrm{NH}_{3} \) and \( \mathrm{H}_{2}\mathrm{O} \). Which of the given statements is FALSE?

1. A
   The \( \mathrm{H}-\mathrm{O}-\mathrm{H} \) bond angle in \( \mathrm{H}_{2}\mathrm{O} \) is smaller than the \( \mathrm{H}-\mathrm{N}-\mathrm{H} \) bond angle in \( \mathrm{NH}_{3} \).
2. B
   The \( \mathrm{H}-\mathrm{C}-\mathrm{H} \) bond angle in \( \mathrm{CH}_{4} \) is larger than the \( \mathrm{H}-\mathrm{N}-\mathrm{H} \) bond angle in \( \mathrm{NH}_{3} \).
3. C
   The \( \mathrm{H}-\mathrm{C}-\mathrm{H} \) bond angle in \( \mathrm{CH}_{4} \), the \( \mathrm{H}-\mathrm{N}-\mathrm{H} \) bond angle in \( \mathrm{NH}_{3} \), and the \( \mathrm{H}-\mathrm{O}-\mathrm{H} \) bond angle in \( \mathrm{H}_{2}\mathrm{O} \) are all greater than \( 90^\circ \).
4. D
   The \( \mathrm{H}-\mathrm{O}-\mathrm{H} \) bond angle in \( \mathrm{H}_{2}\mathrm{O} \) is larger than the \( \mathrm{H}-\mathrm{C}-\mathrm{H} \) bond angle in \( \mathrm{CH}_{4} \).
