Current Question (ID: 8044)

Question:

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

Options:

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

Solution:

$ ext{HINT: Isostructural compounds/ions have the same shape and hybridization.}$ $\text{Explanation:}$ $\text{STEP 1 : The hybridization of Xe in XeF}_2 \text{ is } ext{sp}^3 ext{d} \text{ and the shape of the compound is linear.}$ $\text{The shape of } ext{XeF}_2 \text{ is as follows:}$ $\text{STEP 2:}$ $\text{The hybridization of Te in TeF}_2 \text{ is } ext{sp}^3. \text{ The shape of the compound is bent.}$ $\text{The hybridization of Sb in SbCl}_3 \text{ is } ext{sp}^3. \text{ The shape of the compound is trigonal pyramidal.}$ $\text{The hybridization of B in BCl}_3 \text{ is } ext{sp}^2. \text{ The shape of the compound is trigonal planar.}$ $\text{But in the case of } ext{ICl}_2^{-}, \text{ I hybridization is } ext{sp}^3 ext{d} \text{ and shape is also linear.}$ $\text{STEP 3: Thus, XeF}_2 \text{ is isostructural with } ext{ICl}_2^{-}$
