In Wolf - Kishner reduction, the carbonyl group of aldehydes and ketones is converted into

Options

A. `-CH_2` group
B. `-CH_3` group
C. `-CH_2OH` group
D. `gt CHOH ` group

Answer

**Step-by-Step Solution:**

1. **Understanding Wolf-Kirschner Reduction**: The Wolf-Kirschner reduction is a chemical reaction used to reduce carbonyl groups (such as aldehydes and ketones) to alkanes.

2. **Identifying the Reactants**: In this reaction, hydrazine (NH2NH2) is used as a reducing agent. It reacts with the carbonyl compound (aldehyde or ketone).

3. **Role of Strong Base**: The reaction requires a strong base, typically potassium hydroxide (KOH), to facilitate the reduction process.

4. **Mechanism of Reduction**: The carbonyl group (C=O) of the aldehyde or ketone is converted into a methylene group (–CH2–). This means that the carbonyl oxygen is removed, and the carbon is reduced to a lower oxidation state.

5. **Final Product**: As a result of the Wolf-Kirschner reduction, the carbonyl group is transformed into an alkyl group. Therefore, the final product is an alkane.

6. **Conclusion**: The carbonyl group of aldehydes and ketones is converted into an alkyl group through the Wolf-Kirschner reduction process.

**Final Answer**: In Wolf-Kirschner reduction, the carbonyl group of aldehydes and ketones is converted into an alkyl group.
