JEE Main 2026 — 24 January, Morning Shift — Question 50

Given below are statements about some molecules/ions. Identify the CORRECT statements.

A. The dipole moment value of $\mathrm{NF}_{3}$ is higher than that of $\mathrm{NH}_{3}$ . B. The dipole moment value of $\mathrm{BeH}_{2}$ is zero.

C. The bond order of $\mathrm{O}_{2}^{2-}$ and $\mathrm{F}_{2}$ is same.

D. The formal charge on the central oxygen atom of ozone is -1 .

E. In $\mathrm{NO}_{2}$ , all the three atoms satisfy the octet rule, hence it is very stable.

Choose the correct answer from the options given below :

Option A:
A, B, C, D & E
Option B:
B & C only
Correct
Option C:
B, C & D only
Option D:
A, C & D only

Answer: B

Step-by-step solution

(A) Dipole moment : $\mathrm{NF}_{3}<\mathrm{NH}_{3}$ (B) $\mathrm{BeH}_{2}$ is 'sp' hybridized, linear molecule with zero dipole moment. (C) $\mathrm{O}_{2}^{-2} \Rightarrow$ bond order $=1$ $\mathrm{F}_{2} \Rightarrow$ bond order $=1$ (D) Formal charge on central oxygen atom in $\mathrm{O}_{3}$ is +1 . (E) In $\mathrm{NO}_{2}$ ; nitrogen does not follow octet rule.
