(a) Hydroquinone |
| (v) | |
(g) Anisole |
| (vi) | |
(b) Phenetole |
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.
(vi) Phenetole is an organic compound. It is also known as ethyl phenyl ether. It is volatile in nature and its vapour is explosive in nature.
