-compounds with more than one hydroxyl group are commonly called ‘glycols’. Eg. Ethylene glycol -hydroxyl named as a branch is ‘hydroxy’ Properties: -have strong hydrogen bonding (makes alcohols a liquid) -high boiling points -low freezing points -polar molecules more soluble in water than other hydrocarbons we have seen yet. – Preparation of alcohols: 1. Hydration Reaction (Addition) -add water to alkene or alkyne 2. Fermentation-the production of ethanol from sugars by the action of yeast or bacteria GlucoseEthanol + carbon dioxide (do chemical formulas) Ethanol is the intoxicating substance in alcoholic beverages. Fermentation can take place by distilling (removing water) to make hard alcohols or without distillation to form beer. Wine is higher alcohol content than beer because additional alcohol is added
