Question

Q. Which of the following two are isostructural ?
(A) $X e F_{2}$ and $I F_{2}^{-}$
B $\mathrm{NH}_{3}$ and $\mathrm{BF}_{3}$
c $\mathrm{CO}_{3}^{2-}$ and $\mathrm{SO}_{3}^{2-}$
D $P C l_{5}$ and $I C l_{5}$

Answer 1

Solution:
Isostructural Compounds having same structure and same hybridisation are known as isostructural species, e.g. $X e F^{2}$ and $I F^{2}$ are $s p^{3} d$ hybridised and both have linear shape.
$F-I^{-}-F F-X e-F$
