In the complex acetylbromidodicarbonylbis (triethylphosphine) iron (II), the number of `Fe-C` bond (s) is

Answer

To determine the number of Fe-C bonds in the complex acetylbromidodicarbonylbis(triethylphosphine)iron(II), we will analyze the components of the complex step by step.

### Step 1: Identify the Ligands
The name of the complex provides information about the ligands attached to the iron center:
- **Acetyl** (CH3CO) - This ligand has a carbon atom that will form a bond with iron.
- **Bromido** (Br) - This is a halide ligand and does not contain carbon.
- **Dicarbonyl** (CO) - This indicates there are two carbonyl (C=O) ligands, each containing a carbon atom that will bond with iron.
- **Bis(triethylphosphine)** - This indicates there are two triethylphosphine (P(Et)3) ligands, which do not contain carbon atoms that bond with iron.

### Step 2: Count the Fe-C Bonds
Now, we will count the Fe-C bonds based on the identified ligands:
1. **From the Acetyl Ligand**: There is one Fe-C bond from the acetyl group.
2. **From the Dicarbonyl Ligands**: There are two carbonyl ligands, and each carbonyl forms a bond with iron. Therefore, there are two more Fe-C bonds from the carbonyls.

### Step 3: Total Number of Fe-C Bonds
Adding these together:
- 1 bond from the acetyl ligand
- 2 bonds from the two carbonyl ligands

Thus, the total number of Fe-C bonds is:
\[ 1 + 2 = 3 \]

### Final Answer
The number of Fe-C bonds in the complex acetylbromidodicarbonylbis(triethylphosphine)iron(II) is **3**.
