Which reagent gives pink colour with aldehyde ?

Options

A. Tollen's reagent
B. Schiff reagent
C. Fehling solution
D. Benedict solution

Answer

To solve the question "Which reagent gives pink colour with aldehyde?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify a reagent that reacts with aldehydes to produce a pink color.

2. **Identify Common Reagents**: Some common reagents that react with aldehydes include:
- Tollens' reagent
- Fehling's solution
- Benedict's solution
- Schiff's reagent

3. **Focus on Schiff's Reagent**: Among these, Schiff's reagent is known for its ability to react specifically with aldehydes. When aldehydes are present, Schiff's reagent changes color.

4. **Reaction with Aldehydes**: When an aldehyde is treated with Schiff's reagent, it produces a pink or magenta color. This is due to the formation of a colored complex.

5. **Conclusion**: Therefore, the reagent that gives a pink color with aldehyde is Schiff's reagent.

6. **Select the Correct Option**: Based on the options provided (A, B, C, D), the correct answer is the one that corresponds to Schiff's reagent.

### Final Answer:
The reagent that gives a pink color with aldehyde is **Schiff's reagent**.
