Current Question (ID: 8068)

Question:

From the following pairs, the two species that are not isostructural are :

Options:

1. $\text{PF}_5\text{ and BrF}_5$ (Correct)
2. $\text{PCl}_4^{+}\text{ and SiCl}_4$
3. $\text{CO}_3^{2-}\text{ and NO}_3^{-}$
4. $\text{AlF}_6^{3-}\text{ and SF}_6$

Solution:

$\text{HINT: Isostructural compounds have the same hybridization and shape.}\n\n\text{Explanation:}\n\text{STEP 1:}\n\begin{tabular}{|l|l|l|}\n\hline\n\text{Molecules} & \text{Hybridisation} & \text{Molecular structure} \\\n\hline\n\text{PF}_5 & \text{sp}^3\text{d} & \text{Trigonal Bipyramidal} \\\n\hline\n\text{BrF}_5 & \text{sp}^3\text{d}^2 & \text{Square Pyramidal} \\\n\hline\n\text{PCl}_4^{+}\text{ and SiCl}_4 & \text{sp}^3 & \text{Tetrahderal} \\\n\hline\n\text{CO}_3^{2-}\text{ and NO}_3^{-} & \text{sp}^2 & \text{Trigonal Planar} \\\n\hline\n\text{AlF}_6^{3-}\text{ and SF}_6 & \text{sp}^3\text{d}^2 & \text{Octahedral} \\\n\hline\n\end{tabular}\n\n\text{STEP 2:}\n\n\text{In option 1, both compounds have different hybridization and shape . So, }\n\text{PF}_5\text{ and BrF}_5\text{ are not isostructural.}$
