When vapour of an alcohol are passed over hot reduced copper, alcohol is converted into alkene quickly , the alcohol is

Options

A. Primary
B. Secondary
C. Tertiary
D. None of these

Explanation

To solve the question, we need to analyze the reaction of alcohols with hot reduced copper and determine which type of alcohol is being converted into an alkene.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- When alcohol vapors are passed over hot reduced copper, a reaction occurs that can lead to the formation of alkenes.
- This process typically involves the dehydration of alcohols.

2. **Types of Alcohols**:
- **Primary Alcohols**: These can be oxidized to aldehydes and further to carboxylic acids.
- **Secondary Alcohols**: These can be oxidized to ketones.
- **Tertiary Alcohols**: These do not oxidize easily. Instead, they undergo dehydration to form alkenes when heated.

3. **Identifying the Alcohol**:
- Since the question specifies that the alcohol is converted into an alkene quickly, we need to focus on the type of alcohol that undergoes dehydration rather than oxidation.
- Tertiary alcohols are known to dehydrate readily to form alkenes when heated, while primary and secondary alcohols would typically undergo oxidation.

4. **Conclusion**:
- Based on the above analysis, the alcohol that is converted into alkene quickly when passed over hot reduced copper is a **tertiary alcohol**.

### Final Answer:
The alcohol is a **tertiary alcohol**.
