WebbAliphatic amines have simple hydrocarbon substituents (alkyl groups) while aromatic amines, more commonly referred to as "anilines", have at least one aromatic (benzene) ring substituent. Anilines also are sub-classified as primary, secondary and tertiary based on the total number of carbon-containing substituents as WebbThese are categorised into: primary, secondary and tertiary amines depending on the number of alkyl groups bonded. In primary amines, one alkyl group is attached. Two alkyl groups are attached in secondary amines, and in tertiary amines, three are attached. Just like ammonia, they are weak bases.
