Explanation:
To determine the correct representation for the hypothetical complex chlorodiaquotriammine cobalt (III) chloride, we need to consider the oxidation state of cobalt, the coordination number, and the ligands present in the complex.

Oxidation State:
The Roman numeral III in the name indicates that the cobalt ion has an oxidation state of +3.

Coordination Number:
The coordination number is determined by counting the number of ligands directly bonded to the central metal ion. In this case, the complex is chlorodiaquotriammine cobalt (III) chloride, suggesting a coordination number of 6.

Ligands:
The ligands present in the complex are chloride (Cl-), ammonia (NH3), and water (H2O). Chloride is negatively charged, so it is written as Cl-. Ammonia is neutral, so it is written as NH3. Water is also neutral, so it is written as H2O.

Analysis:
Based on the given options, let's analyze each representation:

a) [CoCl(NH3)3 (H2O)2]Cl2
- This representation indicates that there is one chloride ion coordinated to the cobalt ion, which accounts for the ionic charge of +3. It also shows three ammonia ligands and two water ligands, giving a coordination number of 6.

b) [Co(NH3)3 (H2O)Cl3]
- This representation indicates that there are three chloride ions coordinated to the cobalt ion, which would result in a charge of -3. This does not match the oxidation state of +3 for the cobalt ion.

c) [Co(NH2)3 (H2O)2 Cl]
- This representation includes the ligand NH2, which is not mentioned in the given complex name. Therefore, it is not a valid representation.

d) [Co(NH3)3 (H2O)3]Cl3
- This representation indicates that there are three chloride ions coordinated to the cobalt ion, which would result in a charge of -3. This does not match the oxidation state of +3 for the cobalt ion.

Conclusion:
Based on the analysis, option A ([CoCl(NH3)3 (H2O)2]Cl2) is the correct representation for the hypothetical complex chlorodiaquotriammine cobalt (III) chloride. It matches the given oxidation state, coordination number, and ligands present in the complex.
