Which of the following as a `3^(@)` alcohol?

Options

A. t-Buty1 carbinol
B. 2-Methy1 propan-2-ol
C. 2-Methy1 butan-1-ol
D. isoamy1 alcohol

Explanation

To determine which of the given compounds is a tertiary alcohol, we need to analyze the structure of each compound and identify the type of alcohol it represents. Here’s a step-by-step solution:

### Step 1: Understand the Definition of Tertiary Alcohol
A tertiary alcohol is defined as an alcohol in which the hydroxyl (–OH) group is attached to a carbon atom that is connected to three other carbon atoms.

### Step 2: Analyze Each Compound
1. **Tertiary Butylcarbinol (Neopentyl Alcohol)**:
- Structure: This compound has the –OH group attached to a carbon that is connected to only one other carbon.
- Classification: **Primary Alcohol**.

2. **2-Methylpropane-2-ol**:
- Structure: The –OH group is attached to a carbon that is connected to three other carbon atoms.
- Classification: **Tertiary Alcohol**.

3. **2-Methylbutan-1-ol**:
- Structure: The –OH group is attached to a carbon that is connected to only one other carbon.
- Classification: **Primary Alcohol**.

4. **Isoamyl Alcohol**:
- Structure: The –OH group is attached to a carbon that is connected to only one other carbon.
- Classification: **Primary Alcohol**.

### Step 3: Conclusion
Among the given options, the compound that is classified as a tertiary alcohol is **2-Methylpropane-2-ol**.
