Which of the following compounds is converted to sulfanilic acid by sulfonation?
Options
- ABenzene
- BN-Methylmethanamine
- CAniline
- DPhenol.
Correct answer
C. Aniline
Step-by-step solution
Sulfanilic acid is p-aminobenzenesulfonic acid. Aniline reacts with concentrated sulfuric acid to form anilinium hydrogensulfate. Heating this salt at 453-473 K yields p-aminobenzenesulfonic acid, commonly known as sulfanilic acid, as the major product. Thus, aniline is converted to sulfanilic acid by sulfonation. Answer: Aniline
