The IUPAC name of `CH_3OH` is

Options

A. methanol
B. methyl alcohol
C. methanal
D. hydroxy methane

Explanation

To determine the IUPAC name of the compound CH₃OH, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure**:
- The molecular formula CH₃OH indicates that the compound contains one carbon atom (C), three hydrogen atoms (H), and one hydroxyl group (OH).
- The structure can be represented as:
```
H
|
H - C - OH
|
H
```

2. **Determine the Longest Carbon Chain**:
- In this case, there is only one carbon atom, so the longest carbon chain consists of just that one carbon.

3. **Identify the Functional Group**:
- The presence of the hydroxyl group (OH) indicates that this compound is an alcohol.

4. **Assign the Prefix**:
- The prefix is determined by the number of carbon atoms. Since there is one carbon atom, the prefix is "Meth-".

5. **Determine the Suffix**:
- For alcohols, the suffix is "-ol". Therefore, we will use "ol" as the suffix for the compound.

6. **Combine the Prefix and Suffix**:
- The IUPAC name is formed by combining the prefix and the suffix. Thus, we have:
- Prefix: Meth-
- Suffix: -ol
- Combining these gives us "Methanol".

7. **Final Name**:
- The IUPAC name of CH₃OH is **Methanol**.

### Summary:
The IUPAC name of CH₃OH is Methanol.
