MCQ
The set of meta directing functional groups from the following sets is:
  • A
    $-\mathrm{CN},-\mathrm{NH}_2,-\mathrm{NHR},-\mathrm{OCH}_3$
  • B
    $-\mathrm{NO}_2,-\mathrm{NH}_2,-\mathrm{COOH},-\mathrm{COOR}$
  • ✓
    $-\mathrm{NO}_2,-\mathrm{CHO},-\mathrm{SO}_3 \mathrm{H},-\mathrm{COR}$
  • D
    $-\mathrm{CN},-\mathrm{CHO},-\mathrm{NHCOCH}_3,-\mathrm{COOR}$
✓

Answer

Correct option: C.
$-\mathrm{NO}_2,-\mathrm{CHO},-\mathrm{SO}_3 \mathrm{H},-\mathrm{COR}$
c
All are $-\mathrm{M}$, Hence meta directing groups.
