1. any organic compound containing the hydroxy (-OH) functional group except those in which the OH group is attached to an aromatic ring, which are called phenols. Alcohols are classified as primary, secondary, or tertiary according to whether the carbon atom to which the OH group is attached is bonded to one, two, or three other carbon atoms and as monohydric, dihydric, or trihydric according to whether they contain one, two, or three OH groups; the latter two are called diols and triols, respectively.
