Current Question (ID: 8042)

Question:

$ ext{XeF}_2$ is isostructural with :

Options:

1. $ ext{SbCl}_3$
2. $ ext{BCl}_3$
3. $ ext{TeF}_2$
4. $ ext{ICl}_2^{-}$ (Correct)

Solution:

$ ext{HINT: XeF}_2 \text{ is isostructural with } ext{ICl}_2^{-}$ \n\n $\text{Explanation: Isostructural species are those which have the same shape and hybridisation.}$ \n\n $\begin{tabular}{|l|l|l|l|} \hline \text{Molecules} & \text{Lone pair+ Bond pair} & \text{Hybridisation} & \text{Shape} \\ \hline \text{XeF}_2 & 3+2=5 & ext{sp}^3 ext{d} & \text{Linear} \\ \hline \text{SbCl}_3 & 1+3=4 & ext{sp}^3 & \text{Pyramidal} \\ \hline \text{BCl}_3 & 0+3=3 & ext{sp}^2 & \text{Trigonal Planar} \\ \hline \text{TeF}_2 & 2+2=4 & ext{sp}^3 & \text{Bent} \\ \hline \text{ICl}_2^{-} & 3+2=5 & ext{sp}^3 ext{d} & \text{Linear} \\ \hline \end{tabular}$ \n\n $\text{Thus, XeF}_2 \text{ is isostructural with } ext{ICl}_2^{-}$
