Amines deals with nitrogen-containing organic compounds and their chemical properties. Students learn the classification, nomenclature, preparation and basic nature of aliphatic and aromatic amines. The chapter also covers important reactions of primary, secondary and tertiary amines, along with the chemistry and applications of aniline.
This page covers Amines, chapter 17 of 22 in the Class 12 Chemistry syllabus set by the National Examination Board (NEB). 7 important questions for this chapter are available, each with a full solution.
For numerical and derivation-based chapters like this one, working through past NEB questions is usually more useful than re-reading notes alone — try solving each important question above before checking the solution, then compare your working step by step.
