Which of the following two are isostructural ?

Options

A. `XeF_2 , and IF_2^-`
B. `NH_2, and BF_3`
C. `CO_3^(2-) and SO_3^(2-)`
D. `PCl_5 and IC l_5`

Answer

A

Explanation

Compounds having some structure and same hybridisation are known as isostructural species. E.g. `XeF_2` and `IF_2^-` are `sp^3` d hybridised and both have linear shape.
