Class 12 Chemistry — Chapter 9: Amines
96 practice questions · 32 Easy · 32 Medium · 32 Hard
Practise Class 12 Chemistry Chapter 9, "Amines", with 96 NCERT-aligned multiple-choice questions. The set is split into 32 Easy, 32 Medium and 32 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Amines" is one of the chapters where reactions, named concepts, and balanced numerical work really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Amines, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 12 Chemistry mastery score. A few sample questions are shown below; sign in free to practise all 96.
Key concepts: Amines (Class 12 Chemistry)
This chapter covers amines — their classification, preparation, basic nature, and important reactions including diazonium salt chemistry.
- Classification
- Amines are derivatives of ammonia: primary (1°), secondary (2°) and tertiary (3°), plus aromatic amines like aniline.
- Preparation
- By reduction of nitro compounds/nitriles, ammonolysis of haloalkanes, Gabriel phthalimide synthesis (only 1°) and Hofmann bromamide reaction.
- Basic nature
- Amines are basic due to the lone pair on nitrogen; in water, aliphatic amines are generally more basic than ammonia, aromatic amines less basic (resonance).
- Reactions
- Acylation, alkylation, carbylamine test (1° amines), and reaction with nitrous acid.
- Diazonium salts
- Aromatic 1° amines form diazonium salts (diazotisation); these undergo substitution (Sandmeyer) and coupling reactions to make azo dyes.
💡 Exam tips for Amines
- Order of basicity in water is not simply 3°>2°>1° — solvation and steric effects matter (often 2°>1°≈3° for many aliphatic amines).
- The carbylamine (isocyanide) test is specific to primary amines.
Sample questions
