Properties:

Like ammonia, amines have basic properties, and they react with halogenoalkanes to form longer chains, with the release of a halogen acid. Amines react with carboxylic acids (or similar derivatives such as acyl chlorides) to form amides. The volatile amines have strong unpleasant smells.
