Alcohols can be prepared by hydration of

Options

A. alkenes
B. alkanes
C. alkynes
D. acids

Explanation

To solve the question of how alcohols can be prepared by hydration, we will follow these steps:

### Step-by-Step Solution:

1. **Understand Hydration**: Hydration is a chemical reaction where water (H2O) is added to a compound. This process typically occurs in the presence of an acid catalyst.

2. **Identify the Type of Compounds**: Alcohols can be formed from alkenes through hydration. Alkenes are hydrocarbons that contain at least one carbon-carbon double bond (C=C).

3. **Example of Hydration**: For instance, when ethene (C2H4), an alkene, undergoes hydration in the presence of an acid like sulfuric acid (H2SO4), it reacts with water to form ethanol (C2H5OH), which is an alcohol.

4. **Conclusion**: Therefore, the statement can be concluded that alcohols can be prepared by the hydration of alkenes. Other types of hydrocarbons, such as alkanes (which only have single bonds) and alkynes (which have triple bonds), do not yield alcohols through hydration.

### Final Answer:
Alcohols can be prepared by the hydration of **alkenes**.
