\[Xe{{F}_{2}}\]is structural with

A) \[Te{{F}_{2}}\]            

B)  \[ICl_{2}^{-}\]

C) \[SbC{{l}_{3}}\]           

D)  \[BaC{{l}_{2}}\]

Correct Answer: B

Solution :

 Species having the same number of bond pairs and lone pairs are isostructural (have same structure).

Species	Ip + bp	Structure
\[Xe{{F}_{2}}\]	\[4lp+2bp\]	Linear
\[Te{{F}_{2}}\]	\[2lp+2bp\]	Angular or V-shape
\[ICl_{2}^{-}\]	\[4lp+2bp\]	Linear
\[BaC{{l}_{2}}\]	\[0lp+2bp\]	\[Cl-Ba-Cl(linear)\]

Thus, \[Xe{{F}_{2}},\]is isostructural with\[ICl_{2}^{-}\]and \[BaC{{l}_{2}}.\]
