Consider the molecules \( \mathrm{CH}_{4}, \mathrm{NH}_{3} \) and \( \mathrm{H}_{2} \mathrm{O} \).
P Which of the given statement is false?
W
(1) 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) 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) 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) 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 \( \mathrm{CH}_{4} \).
