Chemistry Question from JEE Main 2025 · 24 January, Shift 1

Which of the following statement is true with respect to $\mathrm{H_2O}$, $\mathrm{NH_3}$ and $\mathrm{CH_4}$?

(A) The central atoms of all the molecules are $sp^3$ hybridized.

(B) The $\mathrm{H-O-H}$, $\mathrm{H-N-H}$ and $\mathrm{H-C-H}$ 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 $\mathrm{CH_4 < NH_3 < H_2O}$.

(D) Both $\mathrm{H_2O}$ and $\mathrm{NH_3}$ are Lewis acids and $\mathrm{CH_4}$ is a Lewis base.

(E) A solution of $\mathrm{NH_3}$ in $\mathrm{H_2O}$ is basic. In this solution $\mathrm{NH_3}$ and $\mathrm{H_2O}$ act as Lowry-Bronsted acid and base respectively.
