Question
Which of the following is isoelectronic pair?
Options
\[\ce{ICI2, ClO2}\]
\[\ce{BrO^{-}_{2}, BrF^{+}_{2}}\]
\[\ce{ClO2, BrF}\]
\[\ce{CN^{-}, O3}\]
Solution
\[\ce{BrO^{-}_{2}, BrF^{+}_{2}}\]
Explanation:
\[\ce{BrO^{-}_{2}}\] (35 + 2 × 8 + 1 = 52)
And
\[\ce{BrF^{+}_{2}}\] (35 + 2 × 9 – 1 = 52)
