Alkanes and alcohols are similar in that they can contain long or short chains of carbon atoms that are surrounded by hydrogen atoms. The special difference between an alkane chain and an alcohol chain is that an alcohol has what is called a hydroxyl group bonded to one of the carbons, replacing a simple hydrogen. The hydroxyl group, which is represented as -OH in chemical formulas, consists of an oxygen atom bonded to a hydrogen atom. The presence of this hydroxyl group dramatically increases the boiling point of an alcohol compared to an alkane of the same length.
