Which of the following is isoelectronic pair?

(i) ICl_{2},ClO_{2}

(ii) BrO_{2}^{-}, BrF_{2}^{+}

(iii) ClO_{2}, BrF

(iv) CN^{-}, O_{3}

Answers (1)

The answer is the option (ii). Isoelectronic pair have same number of electrons

(i)ICl_{2}=53+2\times 17=87

         ClO_{2}=17+16=33

(ii)BrO_{2}^{-}=35+2\times 8+1=52

       BrF_{2}^{+}=35+9\times2-1 = 52

(iii)\; ClO_{2}=17+16=33

           BrF=35+9=44

(iv)CN^{-}=6+7+1=14

             O_{3}=8\times 3=24

Hence, option b is correct.
