Consider the molecules `CH_(4),NH_(3) and H_(2)O`. Which of the given statements is false-

Options

A. The `H-O-H` bond angle in `H_(2)O` is smaller than the `H-N-H` bond angle in `NH_(3).`
B. The `H-C-N` bond angle in `CH_(4)` is larger than the `H-N-H` bond angle in `NH_(3)`.
C. The `H-C-H` bond angle in `CH_(4)` is larger than the `H-C-H` bond angle in `NH_(3)`, and the `H-O-H` bond angle in `H_(2)O` are all greater than `90^(@)`.
D. The `H-O-H` bond angle in `H_(2)O` is larger than the `H-C-H` bond angle in `CH_(4)`.

Answer

D

Explanation

Bond angles in `CH_(4), NH_(3) and H_(2)O` are : `CH_(4)=109.5^(@), NH_(3)=107^(@)` and `H_(2)O=104.5^(@)`
Statement (d) is wrong because bond angle of `H_(2)O` is smaller than that of `NH_(3)`.
