An orgnic compoud with the formula ` C_3 H_5 N` hydrolysis forms a acid which reduces Fehling solution . The compound can be :

Options

A. Ethanenitrile
B. Isocyanoethane
C. Ethoxyethane
D. Propanenitrile

Explanation

To solve the problem, we need to analyze the given organic compound with the formula C₃H₅N and determine which compound it could be based on the information provided.

### Step-by-Step Solution:

1. **Identify the Structure of C₃H₅N**:
- The molecular formula C₃H₅N indicates that the compound is likely unsaturated since it has fewer hydrogens than a saturated compound (which would have C₃H₈N).
- This suggests the presence of either a double bond or a triple bond.

2. **Consider Possible Functional Groups**:
- The compound could be a nitrile (R-C≡N) or an isocyanate (R-N=C=O).
- Let's explore both possibilities.

3. **Case 1: Nitrile (C₂H₅CN)**:
- If we consider the structure as a nitrile (specifically ethyl cyanide, C₂H₅CN), hydrolysis of this compound would yield acetic acid (CH₃COOH) and ammonia (NH₃).
- Acetic acid does not reduce Fehling's solution, as it is not an aldehyde.

4. **Case 2: Isocyanate (C₂H₅NCO)**:
- If we consider the structure as an isocyanate (specifically ethyl isocyanate, C₂H₅NCO), hydrolysis of this compound would yield an amine (ethylamine, CH₃CH₂NH₂) and formic acid (HCOOH).
- Formic acid is known to reduce Fehling's solution because it is an aldehyde in its tautomeric form.

5. **Conclusion**:
- Since the hydrolysis of the isocyanate leads to the formation of formic acid, which can reduce Fehling's solution, the correct answer is that the compound is **isocyanoethane (C₂H₅NCO)**.

### Final Answer:
The compound can be **isocyanoethane (C₂H₅NCO)**.
