Amines Amines are derivatives of ammonia with one or more alkyl groups bonded to the nitrogen. Amines can be classified as primary,secondary or tertiary,meaning one,two and three alkyl groups bonded to the nitrogen respectively E.g. CH3 Primary -NH2 H3C-C-NH2 Amines CH3 CH3 Secondary N-H Amines Tertiary Amines Quaternary ammonium salts have four alkyl groups bonded to the nitrogen,and the nitrogen bears a full positive charge E.g. CH2CH3 H3CH2C-N-CH2CHs r N-CH2CH2CH3 CH2CHa Br Ch19 Amines(landscape) Page ICh19 Amines(landscape) Page 1 Amines Amines are derivatives of ammonia with one or more alkyl groups bonded to the nitrogen.
