JEE Main 2025 — Chemical Bonding And Molecular Structure Question with Solution

Which of the following statement is true with respect to ${\mathrm{H}}_2\mathrm{O},{\mathrm{NH}}_3$ and ${\mathrm{CH}}_4$ ?

A. The central atoms of all the molecules are ${\mathrm{sp}}^3$ hybridized.

B. The $\mathrm{H}-\mathrm{O}-\mathrm{H},\mathrm{H}-\mathrm{N}-\mathrm{H}$ and $\mathrm{H}-\mathrm{C}-\mathrm{H}$ 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 ${\mathrm{CH}}_4<{\mathrm{NH}}_3<{\mathrm{H}}_2\mathrm{O}$.

D. Both ${\mathrm{H}}_2\mathrm{O}$ and ${\mathrm{NH}}_3$ are Lewis acids and ${\mathrm{CH}}_4$ is a Lewis base.

E. A solution of ${\mathrm{NH}}_3$ in ${\mathrm{H}}_2\mathrm{O}$ is basic. In this solution ${\mathrm{NH}}_3$ and ${\mathrm{H}}_2\mathrm{O}$ act as Lowry-Bronsted acid and base respectively.
