BRAINCAKENaming Alcohols
Alcohols are named using IUPAC rules, with the suffix -ol replacing the final -e of the parent alkane.
Step 1. Find the longest carbon chain that contains the carbon bonded to the -OH group. This gives the stem: meth-, eth-, prop-, but-, pent-, hex-.
Step 2. Number the chain from the end that gives the carbon bearing the -OH group the lowest possible number. Put this number just before -ol, for example propan-1-ol and propan-2-ol.
