Answer

To derive the correct structural formula of the compound 5-nitro-3-methoxy-3-methylhexanoyl chloride, we will follow these steps:

### Step 1: Identify the Base Structure
The base structure of the compound is hexanoyl chloride, which is derived from hexanoic acid. Hexanoic acid has a six-carbon chain (C1 to C6).

### Step 2: Number the Carbon Chain
Number the carbon chain from 1 to 6:
- C1: CH3 (methyl group)
- C2: CH2
- C3: CH
- C4: CH2
- C5: CH
- C6: COCl (carbonyl chloride)

### Step 3: Add the Substituents
Now, we need to add the substituents according to their positions:
- **3-methyl**: A methyl group (–CH3) is attached to the third carbon (C3).
- **3-methoxy**: A methoxy group (–OCH3) is also attached to the third carbon (C3).
- **5-nitro**: A nitro group (–NO2) is attached to the fifth carbon (C5).

### Step 4: Construct the Structural Formula
Now, we can construct the structural formula based on the above information:
1. Start with the hexane backbone:
- C1: CH3
- C2: CH2
- C3: C with –CH3 (methyl) and –OCH3 (methoxy)
- C4: CH2
- C5: C with –NO2 (nitro)
- C6: COCl (carbonyl chloride)

The structural formula can be represented as:
```
OCH3
|
CH3-C-CH2-CH-NO2
|
COCl
```

### Final Structural Formula
The final structural formula of 5-nitro-3-methoxy-3-methylhexanoyl chloride is:
```
OCH3
|
CH3-C-CH2-CH-NO2
|
COCl
```
