Amines: These are formally derivatives of ammonia.

This is an MCQ-based quiz on Amines.

This includes Amines that are formally derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of the substituent are attached to one nitrogen atom may be called alkylarylamines).
