`CH_(3)-CHO & C_(6)H_(5)-CO-CH_(3)` can reacts similarly with

Options

A. Tollen's reagent
B. Fehling Solution
C. `I_(2)+KOH`
D. None of these

Explanation

To solve the question regarding the similar reactions of CH₃CHO (acetaldehyde) and C₆H₅COCH₃ (acetophenone), we will analyze their reactivity with the given reagents.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- CH₃CHO is an aldehyde (acetaldehyde).
- C₆H₅COCH₃ is a ketone (acetophenone).

2. **Analyze the Reagents**:
- **Tollens' Reagent**: This reagent is used to distinguish between aldehydes and ketones. Aldehydes react with Tollens' reagent to form a silver mirror, while ketones do not react.
- **Fehling's Solution**: Similar to Tollens' reagent, Fehling's solution is also used to differentiate between aldehydes and ketones. Aldehydes react and produce a red precipitate of cuprous oxide, while ketones do not.
- **I₂ + KOH (Iodoform Test)**: This test is used to identify methyl ketones and certain aldehydes. Both acetaldehyde and acetophenone can react with this reagent.

3. **Determine the Correct Reagent**:
- **Tollens' Reagent**: CH₃CHO reacts, but C₆H₅COCH₃ does not. Thus, this option is incorrect.
- **Fehling's Solution**: CH₃CHO reacts, but C₆H₅COCH₃ does not. Thus, this option is also incorrect.
- **I₂ + KOH**: Both CH₃CHO and C₆H₅COCH₃ can undergo the iodoform reaction. CH₃CHO will yield iodoform (CHI₃) and potassium formate, while C₆H₅COCH₃ will yield iodoform and potassium benzoate.

4. **Conclusion**:
- The only reagent that allows both compounds to react similarly is **I₂ + KOH**.

### Final Answer:
The correct answer is **I₂ + KOH**.
