In chemistry, an Cloze (1): JXUwMDM5JXUwMDBkJXUwMDBmJXUwMDBjJXUwMDA3JXUwMDA3JXUwMDAz is any organic compound in which the hydroxyl functional group (–OH) is bound to a carbon. The term alcohol originally referred to the primary alcohol Cloze (2): JXUwMDNkJXUwMDExJXUwMDFjJXUwMDA5JXUwMDBmJXUwMDAxJXUwMDAz (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic beverages.

Alcohols generally have higher boiling points in comparison to other hydrocarbons having equal molecular masses. This is due to the presence of Cloze (3): JXUwMDMxJXUwMDA3JXUwMDFhJXUwMDExJXUwMDE3JXUwMDFmJXUwMDAyJXUwMDAzJXUwMDA5JXUw MDA2JXUwMDE2JXUwMDE5JXUwMDBkJXUwMDEz hydrogen bonding between hydroxyl groups of alcohol Cloze (4): JXUwMDM1JXUwMDAyJXUwMDAzJXUwMDA5JXUwMDA2JXUwMDE2JXUwMDE5JXUwMDA5JXUwMDE2 .
