Points to Remember
This chapter highlights the importance of amines that are derivatives of ammonia having a pyramidal structure. Students will learn about several methods of preparing amines and their chemical properties. Here are some important points for students to remember:
Amines can be considered as derivatives of ammonia, obtained by replacement of one, two or all the three hydrogen atoms by alkyl and/or aryl groups
Gabriel synthesis is used for the preparation of primary amines. Phthalimide on treatment with ethanolic potassium hydroxide forms potassium salt of phthalimide which on heating with alkyl halide followed by alkaline hydrolysis produces the corresponding primary amine.
The order of boiling points of isomeric amines is primary > secondary > tertiary.
Because of the presence of a lone pair of electrons on the nitrogen atom of -N˙H˙2 group, amines behave as Lewis bases.
All aliphatic amines are more basic than ammonia. In aqueous solution, the order of basic character is (CH3)2NH>CH3NH2>(CH3)3N
The free amine can be obtained from the ammonium salt by treatment with a strong base.
