Caption: Primary, secondary and tertiary alcohols. Animation of molecular models of alcohols with different structures (primary, secondary and tertiary). Atoms are colour-coded spheres: carbon (grey), hydrogen (white) and oxygen (red). Alcohols are hydrocarbons with a hydroxyl (OH) group attached. The primary, secondary and tertiary classification refers to the number of carbon-carbon bonds for the carbon to which the hydroxyl group is connected, with one for primary alcohols, two for secondary alcohols and three (the maximum) for tertiary alcohols. At the start of this clip, from left, the molecules are: the primary alcohol 1-propanol (CH3.CH2.CH2.OH); the secondary alcohol 2-propanol (CH3.CH.(OH).CH3); and the tertiary alcohol 2-methyl-2-propanol (CH3.C.(OH)(CH3).CH3). The latter, the simplest possible tertiary alcohol, is also called tert-butyl alcohol. 2-propanol is the simplest possible secondary alcohol.
