Which of the following species is expected to yield maximum percentage of meta substitution product?

Which of the following species is expected to yield maximum percentage of meta substitution product?
  1. \(\mathrm{ArCH}_{3}\)
  2. \(\mathrm{ArCH}_{2} \mathrm{Cl}\)
  3. \(\mathrm{ArCHCl}_{2}\)
  4. \(\mathrm{ArCCl}_{3}\)

Solution

Among all given reagents \(-\mathrm{CCl}_3\) is strongest electron withdrawing group so it will reduce electron density at ortho and para position and it will direct reacting group at meta position.
So, \(-\mathrm{CCl}_3\) will yield maximum meta product. *
