Question

Which of the following are isostructural pairs? A. SO 4 2 - and CrO 4 2 - B. SiCl 4 and TiCl 4 C. NH 3 and NO 3 - D. BCl 3 and BrCl 3

Aicharya · Accepted Answer

Isostructural species are those which have the same shape and hybridization.

Number of election pair $= \frac{1}{2} [N + V - C + A]$
Where
V= Number of valence electron present in central atom
N= Number of non-monovalent atoms bonded to covalent atom
C= Charge of cation
A= Charge of anion

Hybridisation can be calculated by using this formula then we will be able to find the structure from hybridisation.
