Which of the following statement is true with respect to H2O,NH3\mathrm{H}_2 \mathrm{O}, \mathrm{NH}_3 and CH4\mathrm{CH}_4 ?

A. The central atoms of all the molecules are sp3\mathrm{sp}^3 hybridized.

B. The H−O−H,H−N−H\mathrm{H}-\mathrm{O}-\mathrm{H}, \mathrm{H}-\mathrm{N}-\mathrm{H} and H−C−H\mathrm{H}-\mathrm{C}-\mathrm{H} angles in the above molecules are 104.5∘,107.5∘104.5^{\circ}, 107.5^{\circ} and 109.5∘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 H2O\mathrm{H}_2 \mathrm{O} and NH3\mathrm{NH}_3 are Lewis acids and CH4\mathrm{CH}_4 is a Lewis base.

E. A solution of NH3\mathrm{NH}_3 in H2O\mathrm{H}_2 \mathrm{O} is basic. In this solution NH3\mathrm{NH}_3 and H2O\mathrm{H}_2 \mathrm{O} act as Lowry-Bronsted acid and base respectively.

JEE Main 2025 (Online) 24th January Morning Shift Chemistry - Chemical Bonding & Molecular Structure Question 5 English Explanation

Dipole moment \quad \mathrm{H}_2 \mathrm{O}>\mathrm{NH}_3>\mathrm{CH}_4

H2O&NH3\mathrm{H}_2 \mathrm{O} \& \mathrm{NH}_3 are Lewis Bases

NH3\mathrm{NH}_3 act as Lowry- Bronsted base

Hence, A, B & C are correct
