Intramolecular dehydration of alcohols is carried out with _______ to give ___

Answer

To solve the question "Intramolecular dehydration of alcohols is carried out with _______ to give ___", we need to identify the reagent used for intramolecular dehydration and the product formed.

### Step-by-Step Solution:

1. **Understanding Intramolecular Dehydration**:
- Intramolecular dehydration refers to the process where a molecule loses water (H2O) within itself to form a double bond. This typically occurs in alcohols where the hydroxyl (-OH) group is part of the same molecule that will form the alkene.

2. **Identifying the Reagent**:
- The common reagent used for dehydration reactions, including intramolecular dehydration, is concentrated sulfuric acid (H2SO4). This reagent acts as a dehydrating agent by protonating the alcohol, facilitating the loss of water.

3. **Identifying the Product**:
- The product of intramolecular dehydration of an alcohol is typically an alkene. During the dehydration process, the -OH group is removed along with a hydrogen atom from an adjacent carbon, resulting in the formation of a carbon-carbon double bond.

4. **Final Answer**:
- Therefore, the complete answer to the question is: "Intramolecular dehydration of alcohols is carried out with **concentrated H2SO4** to give **alkene**."

### Summary of the Answer:
- Intramolecular dehydration of alcohols is carried out with **concentrated H2SO4** to give **alkene**.
