Which among the flowing compound(s) is/ are primary alcohol?

Options

A.
B.
C.
D.

Explanation

To determine which among the given compounds is a primary alcohol, we need to understand the definition of primary alcohols. A primary alcohol is characterized by the presence of a hydroxyl (–OH) group attached to a carbon atom that is bonded to only one other carbon atom.

### Step-by-Step Solution:

1. **Identify the Hydroxyl Group (–OH):**
- Look for the –OH group in each of the given compounds. This is the functional group that defines alcohols.

2. **Analyze the Carbon Atom Attached to the –OH Group:**
- For each compound, identify the carbon atom that is directly bonded to the –OH group.

3. **Count the Carbon Atoms Bonded to the Carbon with –OH:**
- Check how many carbon atoms are bonded to the carbon that has the –OH group.
- If this carbon is bonded to only one other carbon atom, then it is classified as a primary alcohol.

4. **Evaluate Each Compound:**
- **Compound 1:** The carbon with –OH is surrounded by 2 carbon atoms. (This is a secondary alcohol.)
- **Compound 2:** The carbon with –OH is surrounded by only 1 carbon atom. (This is a primary alcohol.)
- **Compound 3:** The carbon with –OH is surrounded by 2 carbon atoms. (This is a secondary alcohol.)
- **Compound 4:** The carbon with –OH is surrounded by 3 carbon atoms. (This is a tertiary alcohol.)

5. **Conclusion:**
- Based on the analysis, the only compound that qualifies as a primary alcohol is **Compound 2**.
