NCERT Class 12 Chemistry Chapter 4 Amines Test Mock Test
This free online test covers Chapter 4, Amines, from the NCERT Class 12 Chemistry-II textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.The geometry of an amine molecule is pyramidal, and the C-N-E angle in trimethylamine is 108 degrees rather than 109.5 degrees because:
- AThe nitrogen atom is sp2 hybridised rather than sp3 hybridised
- BNitrogen is more electronegative than carbon, which shortens the bonds
- CThe fourth sp3 orbital of nitrogen holds an unshared pair of electrons, which compresses the bond angles
- DThe three methyl groups repel one another and push the bonds apart
Q2.The compound CH3NHCH2CH3 is named in the IUPAC system as:
- AEthane-1-methylamine
- BN-Methylethanamine
- CMethylethanamine
- DN-Ethylmethanamine
Q3.In reducing nitrobenzene to aniline, reduction with iron scrap and hydrochloric acid is preferred because:
- AHydrogen gas with a nickel, palladium or platinum catalyst does not work on aromatic nitro compounds
- BIron is the only metal that will reduce a nitro group at all
- CThe iron(II) chloride formed is hydrolysed and releases hydrochloric acid, so only a small amount of acid is needed to start with
- DThe reaction gives a secondary amine directly, which is otherwise hard to obtain
