Consider the molecules  ${\mathrm{CH}}_4,{\mathrm{NH}}_3\text{ and }{\mathrm{H}}_2\mathrm{O}\text{. }$Which of the given statements is false? 

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

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

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

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