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 organic molecule `CH3-overset(OH)overset(|)(CH)-overset(O)overset(||)(C)-CH2-CH3`, we need to analyze its structure and determine its reactivity with Tollens' reagent and Fehling's solution.

### Step-by-Step Solution:

1. **Identify the Structure**:
The given molecule can be represented as:
\[ CH_3 - C(OH) - C(=O) - CH_2 - CH_3 \]
This indicates that we have a hydroxyl group (-OH) attached to a carbon that is also connected to a carbonyl group (C=O).

2. **Determine Functional Groups**:
The molecule contains:
- An alcohol group (-OH) which is attached to a carbon that is also adjacent to a carbonyl group (C=O).
- This structure indicates that it is an alpha-hydroxy ketone.

3. **Classify the Alpha-Hydroxy Ketone**:
An alpha-hydroxy ketone can undergo tautomerization to form an aldehyde. However, for the molecule to be classified as a terminal alpha-hydroxy ketone, it should have the hydroxyl group at the end of the carbon chain, which is not the case here.

4. **Tautomerization**:
The molecule can undergo tautomerization, but since it is not a terminal alpha-hydroxy ketone, it will not form a stable aldehyde that can react with Tollens' reagent or Fehling's solution.

5. **Reactivity with Tollens' and Fehling's Tests**:
- **Tollens' Reagent**: This reagent tests for aldehydes. Since the molecule does not form a stable aldehyde, it will not give a positive test.
- **Fehling's Solution**: Similar to Tollens', this reagent also tests for aldehydes. Again, since there is no stable aldehyde formed, it will not give a positive test.

6. **Conclusion**:
Since the molecule does not respond to either Tollens' reagent or Fehling's solution, the correct answer is **none of these**.

### Final Answer:
**None of these**
