(II) |
|
(C) Hydroquinone |
(III) |

(D) p-Cresol |
(IV) |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(I), (B)-(III), (C)-(IV), (D)-(II)
The three dihydroxybenzenes differ only in the positions of the two OH groups on the ring, and each has its own common name: 1,2- is catechol, 1,3- is resorcinol and 1,4- is hydroquinone (quinol). A cresol is a methylphenol; the prefix gives the position of the methyl group relative to OH.
(A) Resorcinol — This matches structure (I). Benzene-1,3-diol: the two OH groups are meta to each other.
(B) Catechol — This matches structure (III). Benzene-1,2-diol: the two OH groups are on adjacent carbons (ortho).
(C) Hydroquinone — This matches structure (IV). Benzene-1,4-diol: the two OH groups are opposite each other (para).
(D) p-Cresol — This matches structure (II). 4-Methylphenol: one OH and one \( \ce{CH3} \) group, para to each other.
