Which of the following amine will give the carbylamine test ?
The Correct Option is A
Solution and Explanation
The Carbylamine test is used to identify primary amines. When a primary amine is reacted with chloroform and alcoholic potassium hydroxide (KOH), an isocyanide (or carbylamine) is formed, which has a very foul smell. This test is not given by secondary or tertiary amines.
Let's analyze the options:
This is a primary amine, which will give a positive carbylamine test.
This is a secondary amine. It will not give the carbylamine test.
This is a tertiary amine. It will not give the carbylamine test.
This compound is not an amine. It will not give the carbylamine test.
From the options given, only option 1 is a primary amine, which will give the carbylamine test. Hence, the correct answer is:
This option corresponds to a primary amine, which is the only type of amine that will produce a positive carbylamine test result.
