Alcohols: It is organic compounds that are characterized by the presence of one, two, or more hydroxyl groups (?OH) that are attached to the carbon atom in an alkyl group or hydrocarbon chain.There are three types of alcohol. Alcohols are classified as primary, secondary, or tertiary alcohols.Primary Alcohols:Those alcohols where the carbon atom of the hydroxyl group (OH) is attached to only one single alkyl group.Examples: 1-Methanol (propanol), 1-ethanol, 1-Butanoletc. Secondary Alcohols:Those where the carbon atom of the hydroxyl group is attached to two alkyl groups on either side.Examples: propane-2-ol, 2-Butanol, 3-Pentanol Tertiary Alcohols:Those which feature hydroxyl group attached to the carbon atom which is connected to 3- alkyl groupsExamples: tert-butyl alcohol etc
