NEET Chemistry Properties of Phenols Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Acetylation of phenols (i) Involves cleavage of C–O bond (b) Preparation from diazonium salts (ii) Produces aspirin (c) Cleavage of C–O bond (iii) Hydrolyzed to phenols (d) Preparation from haloarenes (iv) Involves sodium phenoxide
Choose the correct matching:
a-ii, b-iii, c-i, d-iv
a-iv, b-ii, c-iii, d-i
a-iii, b-ii, c-iv, d-i
a-ii, b-i, c-iv, d-iii
Correct Answer
Detailed Explanation
The acetylation of phenols produces aspirin, while the preparation from diazonium salts is hydrolyzed to phenols. Cleavage of the C–O bond is a specific reaction that mainly occurs in alcohols, but can also occur in phenols under certain conditions. The preparation from haloarenes involves the formation of sodium phenoxide, which is subsequently acidified to yield phenol.
