Which functional group is present in a molecule of `CH_3OH`?

Explanation

To determine the functional group present in the molecule of CH₃OH, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Molecular Formula**: The given molecular formula is CH₃OH. This indicates that the molecule contains carbon (C), hydrogen (H), and oxygen (O).

2. **Draw the Structure**: To understand the functional groups, we can draw the structural formula of CH₃OH. It can be represented as:
```
H
|
H - C - O - H
|
H
```
This shows that the molecule consists of a carbon atom (C) bonded to three hydrogen atoms (H) and one hydroxyl group (–OH).

3. **Identify the Functional Group**: In the structure, we can see that there is a hydroxyl group (–OH) attached to the carbon atom. The presence of this –OH group is characteristic of alcohols.

4. **Classify the Compound**: Since the functional group is a hydroxyl group, we can classify the compound CH₃OH as an alcohol. Specifically, this compound is known as methanol.

5. **Conclusion**: Therefore, the functional group present in the molecule of CH₃OH is the hydroxyl group (–OH).

### Final Answer:
The functional group present in CH₃OH is the hydroxyl group (–OH).
