In the reaction, if X is the reagent and Y is the product, which of the following is not feasible? In the reaction, if X is the reagent and Y is the product, which of the following is not feasible?

Options

  1. AX = Conc. HNO ₃+ Con. H ₂ SO ₄ ; Y =3- Nitrobenzoic acid
  2. BX = Br ₂ / Fe Y =3- Bromobenzoic acid
  3. CX = NaOH , CaO Y = Benzene
  4. DX = CH ₃ Cl / AlCl ₃ Y =3- Methylebenzoic acid

Correct answer

D. X = CH ₃ Cl / AlCl ₃ Y =3- Methylebenzoic acid

Step-by-step solution

This reaction is not feasible because the - COOH group interacts with the lewis acid AlCl ₃ and forms acylium ion instead of the usual electrophilic substitution at the ring.
