The correct Answer is:
To solve the problem of matching the compounds with the oxidation states of cobalt, we will analyze each compound in Column I and determine the oxidation state of cobalt in each case. ### Step-by-Step Solution: **Step 1: Analyze Compound A - [Co(NCS)(NH3)5](SO3)** - Ligands: NCS (−1 charge), NH3 (neutral, 0 charge), SO3 (−2 charge). - Let the oxidation state of cobalt be \( x \). - The equation for the charge balance is: \[ x - 1 + 0 - 2 = 0 \] - Simplifying gives: \[ x - 3 = 0 \implies x = +3 \] **Step 2: Analyze Compound B - [Co(NH3)4Cl2]SO4** - Ligands: NH3 (neutral, 0 charge), Cl (−1 charge), SO4 (−2 charge). - Let the oxidation state of cobalt be \( x \). - The equation for the charge balance is: \[ x + 0 - 1 \times 2 - 2 = 0 \] - Simplifying gives: \[ x - 2 - 2 = 0 \implies x = +4 \] **Step 3: Analyze Compound C - Na4[Co(S2O3)3]** - Ligands: Na (each +1 charge, total +4 for 4 Na), S2O3 (−2 charge). - Let the oxidation state of cobalt be \( x \). - The equation for the charge balance is: \[ 4 + x - 2 \times 3 = 0 \] - Simplifying gives: \[ 4 + x - 6 = 0 \implies x = +2 \] **Step 4: Analyze Compound D - [Co2(CO)8]** - Ligands: CO (neutral, 0 charge). - Let the oxidation state of cobalt be \( x \). - The equation for the charge balance is: \[ 2x + 0 = 0 \] - Simplifying gives: \[ 2x = 0 \implies x = 0 \] ### Summary of Findings: - **Compound A**: Oxidation state of Co = +3 - **Compound B**: Oxidation state of Co = +4 - **Compound C**: Oxidation state of Co = +2 - **Compound D**: Oxidation state of Co = 0 ### Matching with Column II: - A matches with +3 (5) - B matches with +4 (1) - C matches with +2 (4) - D matches with 0 (2) ### Final Code Assignment: - A - 5 - B - 1 - C - 4 - D - 2 Thus, the correct option is **3**.
