NEET Chemistry Properties of Phenols Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Reimer-Tiemann reaction (i) Conjugated diketone (b) Oxidation with chromic acid (ii) Benzene (c) Phenol with zinc dust (iii) Salicylaldehyde (d) Acidic nature of phenol (iv) Phenoxide ion stability
Choose the correct matching:
a-iii, b-i, c-ii, d-iv
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-iv, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
The Reimer-Tiemann reaction introduces a –CHO group at the ortho position of phenol, resulting in salicylaldehyde (a-iii). Oxidation of phenol with chromic acid produces benzoquinone, a conjugated diketone (b-i). Heating phenol with zinc dust converts it to benzene (c-ii). The stability of the phenoxide ion indicates the acidic nature of phenol (d-iv).
