Question

\( p \)-toluidine and benzyl amine can be distinguished by:

• A. Sandmeyer's reaction
• B. Dye test
• C. Molisch test
• D. Gattermann reaction

Hint:

The dye test is commonly used to differentiate between various types of amines based on their ability to react with specific reagents.

Answer 1

The Correct Option is B

Step 1: Understanding the reactions.
The dye test is a method to distinguish between different amines based on their reactivity. \( p \)-toluidine and benzyl amine exhibit different behaviors during the test, which allows their differentiation.
Step 2: Conclusion.
Hence, the dye test is the correct way to distinguish between \( p \)-toluidine and benzyl amine.
Final Answer: \[ \boxed{B} \]
