Current Question (ID: 8042)

Question:

$\text{XeF}_2$ is isostructural with :

Options:

1. $\text{SbCl}_3$
2. $\text{BCl}_3$
3. $\text{TeF}_2$
4. $\text{ICl}_2^{-}$

Solution:

HINT: XeF₂ is isostructural with ICl₂⁻ Explanation: Isostructural species are those which have the same shape and hybridisation. Molecules | Lone pair+ Bond pair | Hybridisation | Shape XeF₂ | 3+2=5 | sp³d | Linear SbCl₃ | 1+3=4 | sp³ | Pyramidal BCl₃ | 0+3=3 | sp² | Trigonal Planar TeF₂ | 2+2=4 | sp³ | Bent ICl₂⁻ | 3+2=5 | sp³d | Linear Thus, XeF₂ is isostructural with ICl₂⁻
