Select the correct statements about aniline.

  1. Ait does not undergo Friedel-Crafts reactions
  2. Bit dissolves in dilute forming anilinium chloride
  3. Cit is converted directly to sulfanilic acid by conc. at room temperature
  4. Dit reacts with water to give 2,4,6-tribromoaniline

Answer: A, B, D

The first three statements are standard: bromine water gives the tribromo derivative, the nitrogen complexes with the Lewis acid, and the amine is protonated by HCl. At room temperature conc. only gives anilinium hydrogensulfate; sulfanilic acid forms when this salt is heated at 453-473 K.
