Which of the following are isostructural pairs ?

A.

SO_4^{2 - }

and

CrO_4^{2 - }

B. SiCl₄, and TiCl₄

C. NH₃ and NO₃^-

D. BCl₃ and BrCl₃

Accepted Answer

Isostructural compounds are those compounds which have same structure as well as same hybridisation.

Formula for find hybridisation : H = (Lone pair + Sigma bond + coordinate bond )

If number of sigma bond (

\sigma

), co-ordinate bond and lone pair are same for given pairs, they are isostructural.
