Question:

What is the type of amine obtained from the ammonolysis of alkyl halides?

Options:

Primary

Primary and secondary

Secondary and tertiary

Primary, secondary and tertiary

Correct Answer:

Secondary and tertiary

Explanation:

The type of amine obtained from the ammonolysis of alkyl halides depends on the number of alkyl groups attached to the nitrogen atom in the amine product. The correct answer is: 3. Secondary and tertiary


1. Primary Amines:
Primary amines have one alkyl group attached to the nitrogen atom.
They are obtained when ammonia (NH₃) reacts with primary alkyl halides.

2. Secondary Amines:
Secondary amines have two alkyl groups attached to the nitrogen atom.
They are obtained when ammonia reacts with secondary alkyl halides.

3. Tertiary Amines:
Tertiary amines have three alkyl groups attached to the nitrogen atom.
They are obtained when ammonia reacts with tertiary alkyl halides.

So, the ammonolysis of alkyl halides can result in the formation of secondary and tertiary amines, depending on the structure of the alkyl halide used in the reaction. Primary amines are not directly formed from the ammonolysis of tertiary alkyl halides.
