Answer

To determine the total number of carbon atoms in the parent carbon chain of the given compound, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure**:
The compound is represented as:
```
CH2 - OH - C - CH - CH3 - CH2 - COOH
```
Here, we have various functional groups and carbon atoms.

2. **Define the Parent Chain**:
The parent carbon chain should include:
- The maximum number of carbon atoms.
- The main functional group (in this case, the carboxylic acid group -COOH).
- Any double or triple bonds if present.

3. **Locate the Functional Group**:
The main functional group in this compound is the carboxylic acid (-COOH). This will help us determine where to start counting the parent chain.

4. **Count the Carbon Atoms**:
Starting from the carboxylic acid group (-COOH), we count the carbon atoms in the longest continuous chain:
- From -COOH (1 carbon)
- The next carbon in the chain (2nd carbon)
- The next carbon connected to it (3rd carbon)
- The next carbon (4th carbon)
- The last carbon connected to the hydroxyl group (5th carbon)

This gives us a total of 5 carbon atoms in the parent chain.

5. **Conclusion**:
Therefore, the total number of carbon atoms in the parent carbon chain is **5**.

### Final Answer:
The total number of carbon atoms in the parent carbon chain is **5**.
