The isoelectronic pair is

Question

The isoelectronic pair is (A) Cl 2 O , ICl 2- (B) ICl 2-, ClO 2 (C) IF 2+, I 3- (D) ClO 2-, ClF 2+

Tardigrade Admin · Accepted Answer

ClO 2-and ClF 2+are isoelectronic species. Number of electrons in ClO 2-=17+16+1=34 electrons Number of electrons in ClF 2+ =17+18-1=34 electrons [Number of electrons in Cl =17, O =8, F =9 ]

Q. The isoelectronic pair is

$C l_{2} O, I C l_{2}^{-}$

$I C l_{2}^{-}, Cl O_{2}$

$I F_{2}^{+}, I_{3}^{-}$

$Cl O_{2}^{-}, Cl F_{2}^{+}$

$Cl O_{2}^{-}$ and $Cl F_{2}^{+}$ are isoelectronic species.
Number of electrons in $Cl O_{2}^{-} = 17 + 16 + 1 = 34$ electrons
Number of electrons in $Cl F_{2}^{+}$ $= 17 + 18 - 1 = 34$ electrons
[Number of electrons in $Cl = 17, O = 8, F = 9$ ]
