Options

A. 2
B. 1
C. 3
D. None

Answer

To determine the number of bridging ligands in octaamine `-mu`-dihydroxodiiron(III)sulphate, we can follow these steps:

### Step 1: Understand the Compound
The compound is octaamine `-mu`-dihydroxodiiron(III)sulphate. Here, "octaamine" indicates that there are eight amine ligands, "dihydroxy" indicates that there are two hydroxide (OH) ligands, and "diiron(III)" indicates that there are two iron (Fe) ions in the +3 oxidation state.

**Hint:** Identify the components of the coordination compound by breaking down its name.

### Step 2: Identify the Ligands
In this compound, the ligands include:
- 8 amine ligands (NH3)
- 2 hydroxide ligands (OH)

**Hint:** List out all the ligands present in the compound based on its name.

### Step 3: Determine the Role of Hydroxide Ligands
The term "bridging ligands" refers to ligands that connect two metal centers. In this case, the two hydroxide (OH) ligands are acting as bridging ligands between the two iron (Fe) ions.

**Hint:** Look for ligands that connect two metal ions in the structure.

### Step 4: Count the Bridging Ligands
Since there are 2 hydroxide ligands connecting the two iron ions, the total number of bridging ligands in the compound is 2.

**Hint:** Count how many ligands are connecting the metal centers.

### Conclusion
The number of bridging ligands in octaamine `-mu`-dihydroxodiiron(III)sulphate is **2**.

**Final Answer:** 2
