Explanation:
(i) Cresols are organic compounds which are methyl phenols. There are three forms of cresol: o-cresol, p-cresol and m-cresol.
(ii) Catechol is also known as pyrocatechol. Its IUPAC name is 1, 2-dihydrobenzene. It is used in the production of pesticides, perfumes and pharmaceuticals.
(iii) Its IUPAC name is 1, 3-dihydroxybenzene. Resorcinol is used to treat acne, seborrheic dermatitis and other skin disorder.
(iv) Hydroquinone is also known as quinol. Its IUPAC name is 1, 4-dihydroxybenzene. It is a white granular solid. It is a good reducing agent.
(v) Anisole or methoxy benzene, is a colourless liquid with a smell reminiscent of an anise seed.
