Which of the following are isostructural pairs?
A. SO4²− and CrO4²−
B. SiCl4 and TiCl4
C. NH3 and NO3−
D. BCl3 and BrCl3
- C and D only
- A and B only
- A and C only
- B and C only
Correct answer: A and B only
Solution
Isostructural pairs are compounds that have the same structural arrangement of atoms. SO4²− and CrO4²− both have tetrahedral geometries, while SiCl4 and TiCl4 also share a similar tetrahedral structure, making both pairs isostructural.
