Nomenclature The IUPAC nomenclature is analogous to that for alcohols,except the -e ending is replaced with-amine. Other substituents on the carbon chain are given numbers,and the prefix N-is used for each substituent on nitrogen E.g NH2 CH3 NH2 CHCH2CHCH: CHCHCH2CH2 old IUPAC names in blue:2-butanamine 3-methyl-1-butanamine new IUPAC names in green:butan-2-amine 3-methylbutan-I-amine 2013 Pearson Education.Inc.
