simple alcohols are named by the IUPAC system as derivatives of the parent alkane, using the suffix -ol:
RULE 1 Select the longest carbon chain containing the hydroxyl group, and derive the parent name by replacing the-e ending of the corresponding alkane with -ol
RULE 2 Number the alkane chain beginning at the end nearer the hydroxyl group
RULE 3 Number the substituents according to their position on the chain,and write the name listing the substituents in alphabetical order:
Some simple and widely occurring alcohols have common names that are accepted by IUPAC. For example:
