Given below are two statements : Statement I: Aniline reacts with con. H 2 SO 4 followed by heating at 453 - 473 K gives p-aminobenzene sulphonic acid, which gives blood red colour in the 'Lassaigne's test'. Statement II: In Friedel - Craft's alkylation and acylation reactions, aniline forms salt with the AlCl 3 catalyst. Due to this, nitrogen of aniline acquires a positive charge and acts as deactivating group. In t

Options

  1. AStatement I is false but statement II is true
  2. BBoth statement I and statement II are false
  3. CStatement I is true but statement II is false
  4. DBoth statement I and statement II are true

Correct answer

D. Both statement I and statement II are true

Step-by-step solution

Aniline reacts with conc . H 2 SO 4 followed by heating at 453 - 473 K gives p-aminobenzene sulphonic acid, which gives blood red colour in the 'Lassaigne's test'Nitrogen, sulphur, and halogens present in organic compounds are detected by Lassaigne's test. Here, a small piece of Na metal is heated in a fusion tube with the organic compound. The principle is that, in doing so, Na converts all the elements present into ionic form. Aniline does not undergo Friedel-Crafts reaction (alkylation and acetylation) due to sa
