An alcohol group can simply be defined as R-OH, with R representing a variable region, normally a carbon chain. An alcohol is simply a carbon chain with an added hydroxyl group. The pattern of nomenclature in alcohols follows the trend of first of all using the basic naming systems to count the number of carbons (methane, ethane, propane, butane etc.) and then adding -ol to the end and removing the e. So, for example, if we had a 4 carbon chain where the alcohol group occurs at the end of the chain we would have butanol. However, if the hydroxyl group was to occur on the second carbon we would simply name it butan-2-ol.
