Options
- AA-IV, B-III, C-II, D-I
- BA-III, B-IV, C-I, D-II
- CA-IV, B-II, C-III, D-I
- DA-II, B-III, C-IV, D-I
Correct answer
A. A-IV, B-III, C-II, D-I
Step-by-step solution
A. [ Co ( NH ₃)₅( NCS )] Cl ₂ and [ Co ( NH ₃)₅( SCN )] Cl ₂ exhibit linkage isomerism because the ambidentate thiocyanate ligand can bind to the metal center through either the nitrogen ( NCS ) or the sulfur ( SCN ) atom. (A IV) B. [ Pt ( NH ₃)₄][ PdCl ₄] and [ Pd ( NH ₃)₄][ PtCl ₄] exhibit coordination isomerism, which occurs when there is an interchange of ligands between cationic and anionic coordination entities of different metal ions present in the complex. (B III) C. [ Co ( NH ₃)₅ Cl ] SO ₄ and [ Co ( NH ₃)
