1. Multiple choice questions.

1. Which of the following compounds is a secondary amine?

(a) Ethylamine
(b) Diethylamine
(c) Triethylamine
(d) Ammonia

Answer: (b) Diethylamine.

2. Which method is commonly used for the preparation of primary amines?

(a) Friedel–Crafts acylation
(b) Gabriel phthalimide synthesis
(c) Wurtz reaction
(d) Kolbe’s synthesis

Answer: (b) Gabriel phthalimide synthesis.

3. Which of the following is a correct order of basicity for amines in aqueous solution?

(a) Primary > Secondary > Tertiary
(b) Secondary > Primary > Tertiary
(c) Tertiary > Secondary > Primary
(d) Tertiary > Primary > Secondary

Answer: (b) Secondary > Primary > Tertiary.

4. Benzene diazonium chloride is mainly used for which type of reactions?

(a) Substitution reaction
(b) Elimination reaction
(c) Rearrangement reaction
(d) Reduction reaction

Answer: (a) Substitution reaction.

2. Very Short Answer (VSA).

1. What is the IUPAC name of CH₃NH₂?

Answer: The IUPAC name of CH₃NH₂ is Methanamine.

2. Name the functional group present in amines.

Answer: Amines contain the –NH₂ (amino) group as their functional group.

3. What is the importance of diazonium salts in organic synthesis?

Answer: Diazonium salts are key intermediates for preparing aromatic compounds by substitution reactions.

3. Short Answer Questions.

1. State the classification of amines based on their structure. Give one example each.

Answer: Amines are classified as primary (one alkyl group, e.g., methylamine), secondary (two alkyl groups, e.g., dimethylamine), and tertiary (three alkyl groups, e.g., trimethylamine). The classification is based on the number of alkyl or aryl groups attached to the nitrogen atom.

2. Explain the basicity order of methylamine, dimethylamine, and trimethylamine in aqueous solution.

Answer: In aqueous solution, the order is: dimethylamine > methylamine > trimethylamine. This is due to the inductive effect and hydrogen bonding. The secondary amine forms stronger hydrogen bonds with water, increasing its basicity compared to primary and tertiary amines.

4. True or False Questions.

1. Gabriel phthalimide synthesis is used to prepare primary amines.

Answer: True.

2. All amines react with nitrous acid to give nitrogen gas.

Answer: False.

3. Aniline is less basic than ethylamine.

Answer: True.

3. Fill in the Blanks Questions.

1. The compound formed by treating aniline with nitrous acid at 0–5°C is ______.

Answer: Benzene diazonium chloride.

2. The Hinsberg test is used for the identification of ______, ______, and ______ amines.

Answer: Primary, secondary, and tertiary.

3. The general formula of primary amine is ______.

Answer: RNH₂.
