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

Options

  1. AA and C only
  2. BB and C only
  3. CA and B only
  4. DC and D only

Correct answer

C. A and B only

Step-by-step solution

Isostructural species are those which have the same shape and hybridization. Number of election pair = 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.
