`CH_3-overset(OH)overset(|)(CH)-overset(O)overset(||)(C )-CH_2 - CH_(3)` will respond to

Options

A. only Fehling solution
B. Only Tollen's reagent
C. Both Tollen's reagent and Fehling solution
D. none of these

Answer

To solve the question regarding the compound \( CH_3-CHOH-C(=O)-CH_2-CH_3 \), we need to identify the functional groups present and determine which tests it will respond to.

### Step-by-Step Solution:

1. **Identify the Structure**:
The given compound can be broken down as follows:
- \( CH_3 \) (methyl group)
- \( CHOH \) (hydroxyl group attached to a carbon)
- \( C(=O) \) (carbonyl group indicating a ketone)
- \( CH_2-CH_3 \) (ethyl group)

This structure indicates that the compound is an alpha-hydroxy ketone because it has a hydroxyl group (–OH) attached to the carbon adjacent to the carbonyl group (C=O).

**Hint**: Look for functional groups in the structure to identify the type of compound.

2. **Understanding Tests**:
- **Tollens' Reagent**: This reagent is used to test for aldehydes and alpha-hydroxy ketones. It gives a positive result (a silver mirror) when reacting with these compounds.
- **Fehling's Solution**: Similar to Tollens', Fehling's solution tests for aldehydes and alpha-hydroxy ketones, providing a positive result (red precipitate) for these functional groups as well.

**Hint**: Familiarize yourself with the reagents and the types of compounds they test for.

3. **Conclusion**:
Since the compound \( CH_3-CHOH-C(=O)-CH_2-CH_3 \) is an alpha-hydroxy ketone, it will give positive tests for both Tollens' reagent and Fehling's solution.

Therefore, the answer to the question is that the compound will respond positively to both Tollens' reagent and Fehling's solution.

**Final Answer**: The compound will respond to both Tollens' reagent and Fehling's solution.
