What is the IUPAC name of the compound?
`H_3 C - underset(Cl) underset(|)CH-CH_2 - CH_2-underset(Cl)underset(|)CH-CH_3`

Options

A. 2-chloro-5-hydroxyhexane
B. 2-chlorohexan-5-ol
C. 2-hydroxy-5-chlorohexane
D. 5-chlorohexan-2-ol

Explanation

To determine the IUPAC name of the given compound, we will follow these steps:

### Step 1: Identify the structure
The compound is represented as:
```
H3C - Cl
|
CH
|
CH2 - CH2
|
Cl
|
CH
|
CH3
```
This structure indicates that we have a carbon chain with two chlorine substituents.

### Step 2: Determine the longest carbon chain
The longest continuous carbon chain in the structure has 6 carbon atoms. Therefore, the parent chain is hexane.

### Step 3: Number the carbon chain
We will number the carbon chain from the end closest to the first substituent (the chlorine atoms). The numbering is as follows:
```
1 - H3C
2 - Cl
3 - CH
4 - CH2
5 - Cl
6 - CH3
```
This gives us the positions of the chlorine substituents.

### Step 4: Identify the substituents
The two chlorine substituents are located at positions 2 and 5 of the hexane chain.

### Step 5: Combine the information for the IUPAC name
The IUPAC name is constructed by listing the substituents in alphabetical order, followed by the name of the parent chain. Since both substituents are chlorine, we will use the prefix "dichloro" to indicate that there are two chlorine atoms.

Thus, the IUPAC name is:
**2,5-dichlorohexane**

### Summary of the steps:
1. Identify the structure and draw it out.
2. Determine the longest carbon chain (hexane).
3. Number the carbon chain from the end nearest to the first substituent.
4. Identify the positions of the substituents (Cl at positions 2 and 5).
5. Combine the information to write the IUPAC name.
