Which of the following compounds is converted to sulfanilic acid by sulfonation?

Options

  1. ABenzene
  2. BN-Methylmethanamine
  3. CAniline
  4. 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 453−473453-473 K yields p-aminobenzenesulfonic acid, commonly known as sulfanilic acid, as the major product.

Thus, aniline is converted to sulfanilic acid by sulfonation.
