This functional group can be added to an alkene in a Markovnikov fashion by adding mercuric acetate and water, followed by sodium borohydride in a sodium hydroxide solution in a process called oxymercuration. When compounds containing this functional group are of low mass, zinc chloride can be used to classify them in the Lucas test. Secondary ones can be oxidized into ketones, and when yeast cells undergo fermentation, they produce carbon dioxide and a compound which contains this functional group. Name this functional group with general formula R-OH, examples of which include ethanol and methanol.
