Question

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

A. The dipole moment value of ${NF}_{3}$ is higher than that of ${NH}_{3}$ .
B. The dipole moment value of ${BeH}_{2}$ is zero.
C. The bond order of $O_{2}^{2 -}$ and $F_{2}$ is same.
D. The formal charge on the central oxygen atom of ozone is −1.
E. In ${NO}_{2}$ , all the three atoms satisfy the octet rule, hence it is very stable.

Choose the correct answer from the options given below: [2026]

Smart Achievers · Accepted Answer

(2)

(A) Dipole moment : ${NF}_{3} < {NH}_{3}$

(B) ${BeH}_{2}$ is $' sp'$ hybridized, linear molecule with zero dipole moment.

(C) $O_{2}^{2 -} \Rightarrow$ bond order $= 1$
$F_{2} \Rightarrow$ bond order $= 1$

(D) Formal charge on central oxygen atom in $O_{3}$ is $+ 1$

(E) In ${NO}_{2}$ , nitrogen does not follow octet rule.
