Which of the following is a pair of isoelectronic species?
Options
(a) Cl₂O₃, ICl₂⁻
(b) ICl₂⁻, CIO₂
(c) IF₂⁺, I₃⁻
(d) CIO₂⁻, CIF₂⁺
Correct Answer:
CIO₂⁻, CIF₂⁺
Explanation:
Number of electrons in CIO₂⁻ = 17+ 16+ 1 = 34 electrons.
Number of electrons in CIF₂⁺ = 17+ 18- 1 = 34 electrons.
Hence, CIO₂⁻ and CIF₂⁺ are isoelectronic species.
