Question

Among the interhalide species $IF_{2}^{\Theta},$ IF₃, $IF_{4}^{\Theta}$and IF₇

• A. All iodine centres are either sp³d or sp³d²hybridised
• B. The minimum angular separation between fluorine atoms is 60°
• C. The anionic species are both isoelectronic and isostructural to XeF₂ and XeF₄
• D. There is no species having a single lone pair of electrons

Answer 1

Answer: (C)

The anionic species are both isoelectronic and isostructural to XeF₂ and XeF₄

Answer 2

Hybridisation and structure of $IF_{2}^{–}$® sp³d & linear

Hybridisation and structure of XeF₂ ® sp³d & linear

So Both XeF₂ and $IF_{2}^{–}$ are isostructural and isoeletronic

Hybridisation and structure of $IF_{4}^{–}$ ® sp³d² & square

Planar

Hybridisation and structure of XeF₄ ® sp³d² & square

Planar

̃ Both XeF₄ and $IF_{4}^{–}$are isoelectronic and isostructural
