Introduction Alkanols (or alcohols) are a homologous series of organic compounds with the general formula CnH2n+1OH or simply ROH. Their molecules consist of a functional group — the hydroxyl group (—OH) joined to an alkyl group (R—). They can be used to fuel cars as they are flammable. Unlike alkanes, alkenes and alkynes, alkanols are
