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 |
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).
