Amines

Amines are organic compounds with a nitrogen atom having a lone pair of electrons on it. They are derived from ammonia (NH3) wherein hydrogen atoms are substituted by an aryl or alkyl group.

Question

7. Amines (R-NH2, R₂NH, or R³N) are the organic analogs of ammonia (NH3) where one or more of
the hydrogens on the nitrogen has been replaced by an alkyl group (R). Like ammonia, amines are
basic with pKb's in the same range as the pka's of carboxylic acids. Amines readily form their water
soluble conjugate acids in the presence of 5% aqueous HC1. Work out an extraction procedure to
separate the following compounds.
