Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(I), (B)-(III), (C)-(IV), (D)-(II)

The correct answer is Option (1) → (A)-(I), (B)-(III), (C)-(IV), (D)-(II)

Core Concept:

These compounds are positional isomers of dihydroxybenzene and substituted phenol.

Resorcinol has OH groups at meta position (1,3)

Catechol has OH groups at ortho position (1,2)

Hydroquinone has OH groups at para position (1,4)

p-Cresol has OH and CH₃ at para position

Option-wise Explanation:

Resorcinol

Resorcinol is meta-dihydroxybenzene.

The two OH groups are located at positions 1 and 3.

This corresponds to the meta arrangement on the benzene ring.

Thus it matches with structure (I).

Catechol

Catechol is ortho-dihydroxybenzene.

The OH groups are adjacent at positions 1 and 2.

This is the ortho configuration.

Thus it matches with structure (III).

Hydroquinone

Hydroquinone is para-dihydroxybenzene.

The OH groups are opposite each other at positions 1 and 4.

This is the para configuration.

Thus it matches with structure (IV).

p-Cresol

p-Cresol is para-methylphenol.

It contains one OH group and one CH₃ group opposite each other.

This matches the para substituted structure.

Thus it matches with structure (II).
