Which of the following structures represents cyclopenty1 methy1 carbino1?

Options

A.
B.
C.
D.

Explanation

To determine which structure represents cyclopentyl methylcarbinol, we can follow these steps:

### Step 1: Understand the Components of the Compound
- **Cyclopentyl**: This refers to a cyclopentane ring (a five-membered carbon ring) with a substituent.
- **Methylcarbinol**: This indicates a carbon atom bonded to a hydroxyl group (–OH) and a methyl group (–CH3). The structure can be represented as CH3–C(OH)–.

### Step 2: Identify the Carbinol Group
- The carbinol group is characterized by the presence of a hydroxyl group (–OH) attached to a carbon atom. In this case, the carbon atom is also bonded to a methyl group (–CH3).

### Step 3: Construct the Structure
- The structure of cyclopentyl methylcarbinol can be constructed by combining the cyclopentyl group and the methylcarbinol group.
- The carbon from the methylcarbinol will be connected to the cyclopentyl group, and the hydroxyl group will be attached to this carbon.

### Step 4: Draw the Structure
- Draw a five-membered carbon ring representing cyclopentane.
- Attach a carbon (from the methylcarbinol) to one of the carbons in the cyclopentane ring.
- Attach a methyl group (–CH3) and a hydroxyl group (–OH) to this carbon.

### Step 5: Analyze the Given Options
- Compare the drawn structure with the provided options.
- Identify which option correctly represents the structure of cyclopentyl methylcarbinol.

### Conclusion
After analyzing the options, the correct structure that represents cyclopentyl methylcarbinol is option C.
