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:

Accepted Answer

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.
