Solution

Q.
The number of molecules or ions from the following, which do not have odd number of electrons are ________. [2023]

(A) ${NO}_{2}$ (B) ${ICl}_{4}^{-}$

(C) ${BrF}_{3}$ (D) ${ClO}_{2}$

(E) ${NO}_{2}^{+}$ (F) NO

Ans.
(3)

Species Total electron

${NO}_{2}$ 23

${ICl}_{4}^{-}$ 122

${BrF}_{3}$ 62

${ClO}_{2}$ 33

${NO}_{2}^{+}$ 22

$NO$ 15

${ICl}_{4}^{-}, {BrF}_{3}$ and ${NO}_{2}^{+}$ are not having odd number of electrons.

${NO}_{2}, {ClO}_{2}$ and NO have odd number of electrons.
