Which reagents would you use to carry out the reaction Ethyl benzene 2 and 4 - chloro 1 - ethyl benzene?

Options

  1. ACl ₂ , light and heat
  2. BCl ₂, FeCl ₃
  3. CSOCl ₂
  4. DC ₂ H ₅ Cl , AlCl ₃

Correct answer

B. Cl ₂, FeCl ₃

Step-by-step solution

Ethyl in o/p directing group. Direct chlorination of ethyl benzene with Cl ₂ / FeCl ₃ would give mixture of 2 and 4-chloroethyl benzene.
