Simple aliphatic amine groups
Webb14 apr. 2024 · In common system an aliphatic amine is named by prefixing alkyl group to amine i.e., alkylamine as one word. In IUPAC system, amines are named as alkanamines, derived by replacement of 'e' of alkane by the word amine. 1. CH3-NH2 - Methanamine 2. CH3-CH (NH2)-CH2-CH3 - Butan-2-amine 3. H2N-CH2-CH2-CH2-NH2 - Propane-1, 3 … 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
