Identify ortho and para directing groups from the following : ( array cccc - CHO , & - NHCOCH ₃, & - OCH ₃, & - SO ₃ H I & II & III & IV array )

Options

  1. AIII, IV
  2. BII, III
  3. CII, IV
  4. DI, IV

Correct answer

B. II, III

Step-by-step solution

Generally, electron withdrawing groups such as - ( CHO ) and ( SO ₃ H ) group are meta directing group. Whereas electron donating groups such as (- OCH ₃,- NHCOCH ₃ ) group are ortho and para directing group. These groups increase the electron density particularly at ortho and para position of the sign as given below :
