Rules for IUPAC nomenclature selection of carbon chain: select the longest carbon chain which includes primary functional group with more substituents If a double or triple bond is Present, the parent chain must contain it Numbering: numbering would starts from primary functional group if no primary functional group beginning at the end nearer the first substituent If a double or triple bond is Present in parent chain,numbering begin at the end nearer the double or triple bond Naming: Name all the substituents and list them in alphabetical order when writing the name If more than one of the same kind of substituents, number each and use one in the prefixes di, tri-, tetra-, and so on Prefix-Parent Suffix primary functional group Number of carbons what are substituents cyclohex isopropyl and methyl (ene)
