(i) Derivatives of ammonia
(ii) Obtained by the replacement of one, two or all the three H-atoms of ammonia by alkyl and/or aryl group
(iii) Structure of Amines
Nitrogen on amines is sp3 hybridised.
Geometry − Pyramidal
Example: Pyramidal shapes of trimethylamine
Classification: Primary (1 ), secondary (2 ) and tertiary (3 )
(i) If one H-atom of NH3 is replaced by R or Ar, RNH2 or ArNH2 is obtained (primary amine, 1°).
(ii) If two H-atoms of NH3 or one H-atom of RNH2 are replaced by alkyl or aryl group (R′), R2NH is obtained (secondary amine, 2°).
(iii) On the replacement of another hydrogen atom by alkyl or aryl group, R3N is obtained (tertiary amine, 3°).
