Question

Which of the following statement is true with respect to $H_{2} O, NH_{3}$ and $CH_{4}$ ?
A. The central atoms of all the molecules are $sp^{3}$ hybridized.
B. The $H - O - H, H - N - H$ and $H - C - H$ angles in the above molecules are $104. 5^{\circ}, 107. 5^{\circ}$ and $109. 5^{\circ}$ , respectively.
C. The increasing order of dipole moment is $CH_{4} < NH_{3} < H_{2} O$ .
D. Both $H_{2} O$ and $NH_{3}$ are Lewis acids and $CH_{4}$ is a Lewis base.
E. A solution of $NH_{3}$ in $H_{2} O$ is basic. In this solution $NH_{3}$ and $H_{2} O$ act as Lowry-Bronsted acid and base respectively.
Choose the correct answer from the options given below:

Options:

Answer:

A

Solution:

Dipole moment $H_{2} O > NH_{3} > CH_{4}$
$H_{2} O & NH_{3}$ are Lewis Bases
$NH_{3}$ act as Lowry- Bronsted base
Hence, A, B & C are correct
