Question

The carbamylation reaction is given by aliphatic

• A. primary amine
• B. secondary amine
• C. tertiary amine
• D. quaternary ammonium salt

Hint:

Carbamylation involves primary amines reacting with isocyanates to form carbamate derivatives.

Answer 1

The Correct Option is A

Step 1: Understanding carbamylation.
The carbamylation reaction involves the reaction of a primary amine with isocyanates to form a carbamate (urethane) derivative. This reaction typically occurs with primary amines.

Step 2: Conclusion.
Thus, the correct answer is option (A).

Final Answer: \[ \boxed{\text{(A) primary amine}} \]
