Multiple choice

During the preparation of acetanilide from aniline, a small amount of Zn is added to the reaction mixture because

  1. zinc induces the precipitation

  2. zinc prevents the reduction of aniline during the reaction

  3. zinc reduces the coloured impurities in the aniline and also prevents its oxidation during the reaction

  4. zinc forms the white crystalline complex with aniline

  5. Only (3) and (4)

C Correct answer
Explanation

This option is correct because acetanilide are formed by the aniline due to the addition of zinc, this reduces the coloured impurities of the aniline and also prevents the oxidation of the reaction.
