Hydrocarbons are formed when aldehydes and ketones are reacted with amalgamated zinc and conc. HCl. The reaction is called

Options

A. Cannizzaro reaction
B. Clemmensen reduction
C. Rosenmund reduction
D. Wolff-Kishner reduction.

Answer

To solve the question regarding the reaction of aldehydes and ketones with amalgamated zinc and concentrated hydrochloric acid, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are aldehydes and ketones, which are types of carbonyl compounds.

2. **Understand the Reaction Conditions**:
- The reaction is carried out using amalgamated zinc (Zn/Hg) and concentrated hydrochloric acid (HCl). Amalgamated zinc is a reducing agent.

3. **Recognize the Type of Reaction**:
- The reaction involves the conversion of the carbonyl group (C=O) present in aldehydes and ketones into a hydrocarbon group (C-H). This indicates that a reduction process is taking place.

4. **Name the Reaction**:
- The specific reaction that converts carbonyl compounds (aldehydes and ketones) into hydrocarbons using amalgamated zinc and concentrated HCl is known as the Clemenson reduction.

5. **Conclude the Answer**:
- Therefore, the reaction is called the Clemenson reduction.

### Final Answer:
The reaction is called the **Clemenson reduction**.
