JEE Main 2025 — 24 January, Morning Shift — Question 41

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 CH4<NH3<H2O\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.

Choose the correct answer from the options given below :

  1. Option A:

    A, B and C only

    Correct
  2. Option B:

    C, D and E only

  3. Option C:

    A, D and E only

  4. Option D:

    A, B, C and E only

Answer: A

Step-by-step solution

figure

Dipole moment H2O>NH3>CH4\mathrm{H}_{2} \mathrm{O}>\mathrm{NH}_{3}>\mathrm{CH}_{4}

H2O\mathrm{H}_{2} \mathrm{O} & NH3\mathrm{NH}_{3} are Lewis Bases

NH3\mathrm{NH}_{3} act as Lowry- Bronsted base

Hence, A, B & C are correct
