Consider the following sulfur donor atom bearing bidentate ligand where X and name of ligands are given in following columns 
Correct match of entries given in two columns is
| X | Ligand name |
|---|---|
| A. $\mathrm{NR_2}$ | I. Dithiocarbonate |
| B. OR | II. Dithiocarbamate |
| C. $\mathrm{O^{-}}$ | III. Xanthate |
| D. SR | IV. Thioxanthate |
(a)A-II, B-III, C-I, D-IV
(b)A-III, B-II, C-IV, D-I
(c)A-I, B-II, C-III, D-IV
(d)A-IV, B-I, C-II, D-III
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
With X = NR₂ the ligand is a dithiocarbamate; OR gives a xanthate; O⁻ gives dithiocarbonate; SR gives a trithiocarbonate (thioxanthate). A-II, B-III, C-I, D-IV (a).
