The number of molecules or ions from the following, which do not have odd number of electrons are _________.
(A) NO2_22
(B) ICl4−_4^ - 4−
(C) BrF3_33
(D) ClO2_22
(E) NO2+_2^ + 2+
(F) NO
Only ICl4−, BrF3\mathrm{ICl}_4^{-}, \mathrm{BrF}_3ICl4−, BrF3 and NO2+\mathrm{NO}_2^{+}NO2+have even number of electrons.
NO2 ⇒ 23 e− ; ICl4− ⇒ 122 e− ; BrF3 ⇒ 62 e− ; ClO2 ⇒ 33 e− ; NO2+ ⇒ 22 e− ; NO ⇒ 15 e− \begin{aligned} & \mathrm{NO}_2 \Rightarrow 23 e^{-} ; \\ & \mathrm{ICl}_4^{-} \Rightarrow 122 e^{-} ; \\ & \mathrm{BrF}_3 \Rightarrow 62 e^{-} ; \\ & \mathrm{ClO}_2 \Rightarrow 33 e^{-} ; \\ & \mathrm{NO}_2^{+} \Rightarrow 22 e^{-} ; \\ & \mathrm{NO} \Rightarrow 15 e^{-} \end{aligned} NO2 ⇒ 23 e− ; ICl4− ⇒ 122 e− ; BrF3 ⇒ 62 e− ; ClO2 ⇒ 33 e− ; NO2+ ⇒ 22 e− ; NO ⇒ 15 e−
