NEET Chemistry Properties of Phenols Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Reimer-Tiemann reaction | (i) Conversion to benzene |
| (b) Oxidation with chromic acid | (ii) Formation of benzoquinone |
| (c) Reaction with zinc dust | (iii) Introduction of –CHO group |
| (d) Electrophilic substitution | (iv) Activation of aromatic ring |
a-iii, b-ii, c-i, d-iv
a-ii, b-iv, c-iii, d-i
a-iv, b-iii, c-ii, d-i
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
The Reimer-Tiemann reaction introduces a –CHO group at the ortho position of the benzene ring, while oxidation with chromic acid produces benzoquinone. Heating phenol with zinc dust converts it to benzene, and electrophilic substitution is activated by the alkoxy group.
