Account for the following statement- Aniline does not undergo Friedel-Crafts reaction.

Options

  1. AAniline is not a suitable electrophile in Friedel-Crafts reactions.
  2. BAniline being a Lewis base forms a complex with AlCl 3 , a Lewis acid. As a result, nitrogen of aniline become
  3. CAniline is too polar to participate in Friedel-Crafts reactions.
  4. DAniline is a strong Lewis base and therefore inhibits the Friedel-Crafts reaction mechanism.

Correct answer

B. Aniline being a Lewis base forms a complex with AlCl 3 , a Lewis acid. As a result, nitrogen of aniline become

Step-by-step solution

Correct Option is : (B) Aniline being a Lewis base forms a complex with AlCl 3 , a Lewis acid. As a result, nitrogen of aniline becomes positively charged and acts as a strong deactivating group for electrophilic substitution reaction. As a result,aniline does not undergo Friedel Crafts reaction.
