Which of the following would not give 2-phenylbutane as the major product in a Friedel-Crafts alkylation reaction ?

Options

  1. A1-butene + HF
  2. B2-butanol + H ₂ SO ₄
  3. CButanoyl chloride + AlCl ₃ then Zn , HCl
  4. DButyl choloride + AlCl ₃

Correct answer

C. Butanoyl chloride + AlCl ₃ then Zn , HCl

Step-by-step solution

The Friedal-crafts alkylation reaction will give propyl phenyl ketone which further on Clemmenson's reduction will give butyl benzene
