Alcohol, phenol, and ether are the classes of organic compounds that emanate from the hydrocarbons. When the hydroxy group replaces a hydrogen atom of the aliphatic hydrocarbon, it is referred to as alcohol. In contrast, if the hydroxy group replaces a hydrogen atom of the benzene, it is referred to as phenols. In contrast, an ether is formed when the two alkyl groups are joined together by the oxygen atom.
