Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by –OH group The subsitution of a hydrogen atom in a hydrocarbon by an alkoxy or aryloxy group (R–O/Ar–O) yields another class of compounds known as 'ethers', for example, CH3OCH3 (dimethyl ether)

– in alcohols, a hydroxyl group is connected to a carbon atom – in phenols, —OH is connected to a benzene ring (The “parent” molecule of this class is also named phenol: PhOH or C6H5OH ) When two carbon groups are connected by single bonds to an oxygen, this is classified as the ether functional group
