Acetone shows similarity with acetaldehyde in reacting to-

Options

A. Schiff’s reagent
B. Fehling solution
C. Grignard reagent
D. Tollen’s reagent

Answer

To determine the similarity in reactivity between acetone and acetaldehyde, we need to analyze their reactions with various reagents.

### Step-by-Step Solution:

1. **Identify the Functional Groups**:
- Acetaldehyde (CH3CHO) contains an aldehyde functional group.
- Acetone (CH3COCH3) contains a ketone functional group.

2. **Reactions with Schiff's Reagent**:
- Schiff's reagent reacts primarily with aldehydes to produce a bright red color.
- While acetone (ketone) can react with Schiff's reagent, it is not typically used for this purpose. Therefore, this similarity is not significant.

3. **Reactions with Fehling's Solution**:
- Fehling's solution is known to react with aldehydes to produce a red precipitate of copper(I) oxide.
- Ketones do not react with Fehling's solution. Hence, this is not a point of similarity.

4. **Reactions with Tollens' Reagent**:
- Tollens' reagent (ammoniacal silver nitrate) reacts with aldehydes to form a silver mirror and oxidizes the aldehyde to a carboxylic acid.
- Ketones do not react with Tollens' reagent. Therefore, this is also not a similarity.

5. **Reactions with Grignard Reagent**:
- Grignard reagents (e.g., CH3MgBr) react with both aldehydes and ketones through nucleophilic addition.
- For acetaldehyde, the reaction with Grignard reagent produces a secondary alcohol after hydrolysis.
- For acetone, the reaction with Grignard reagent also produces a tertiary alcohol after hydrolysis.
- This indicates that both acetaldehyde and acetone can react with Grignard reagents, demonstrating a similarity in their reactivity.

6. **Conclusion**:
- The only significant similarity in reactivity between acetone and acetaldehyde is their reaction with Grignard reagents.

### Final Answer:
Acetone shows similarity with acetaldehyde in reacting to **Grignard Reagent**.
