Give IUPAC name of the compund given below:
`CH_3-underset(Cl)underset(|)CH-CH_2-CH_2-underset(OH)underset(|)CH-CH_3`

Options

A. 2-Chloro-5-hydroxyhexane
B. 2-Hydroxy-5-chlorohexane
C. 5-Chlorohexan-2-ol
D. Chlorohexan-5-ol

Answer

To determine the IUPAC name of the compound given, we will follow a systematic approach:

### Step-by-Step Solution:

1. **Identify the Longest Carbon Chain:**
- The compound has a total of 6 carbon atoms in the longest continuous chain.
- This means the base name will be derived from "hex" (for six carbons).

2. **Identify the Functional Groups:**
- The compound contains two functional groups: a hydroxyl group (-OH) and a chlorine atom (Cl).
- The hydroxyl group (-OH) is an alcohol, which takes priority over the chlorine atom in naming.

3. **Number the Carbon Chain:**
- Start numbering the carbon chain from the end closest to the hydroxyl group to give it the lowest possible number.
- In this case, numbering from the left gives the hydroxyl group the number 2.
- The numbering will be:
- C1: CH3
- C2: CH
- C3: CH2
- C4: CH2
- C5: CH
- C6: CH3

4. **Determine the Position of Functional Groups:**
- The hydroxyl group (-OH) is on carbon 2, so we will use "2-ol" as the suffix.
- The chlorine atom (Cl) is on carbon 5, so we will use "5-chloro" as the prefix.

5. **Combine the Information:**
- The name will be constructed by combining the prefix, base name, and suffix.
- The base name is "hex" (for six carbons), and since it is an alcohol, we replace the "e" in "hexane" with "ol".
- Therefore, the complete name is: **5-chloro-hexan-2-ol**.

### Final Answer:
The IUPAC name of the compound is **5-chlorohexan-2-ol**.
