Options
- AA-I, B-II, C-III, D-IV
- BA-II, B-I, C-IV, D-III
- CA-II, B-I, C-III, D-IV
- DA-II, B-IV, C-I, D-III
Correct answer
B. A-II, B-I, C-IV, D-III
Step-by-step solution
A. [ Co ( NH ₃)₆][ Cr ( CN )₆] consists of both a complex cation and a complex anion. It exhibits coordination isomerism due to the interchange of ligands between the two coordination spheres. B. [ Co ( NH ₃)₅ Br ] SO ₄ exhibits ionization isomerism as it can exchange the coordinated bromide ion with the sulfate counter ion to form [ Co ( NH ₃)₅ SO ₄] Br . C. [ Cr ( ox )₃]³⁻ is an octahedral complex with three bidentate ligands. It lacks a plane of symmetry and exists as non-superimposable mirror images, thus exhib
