General Organic Chemistry Question 5
Question 5 - 2024 (01 Feb Shift 2)
The set of meta directing functional groups from the following sets is:
(1) $-\mathrm{CN},-\mathrm{NH}{2},-\mathrm{NHR},-\mathrm{OCH}{3}$
(2) $-\mathrm{NO}{2},-\mathrm{NH}{2},-\mathrm{COOH},-\mathrm{COOR}$
(3) $-\mathrm{NO}{2},-\mathrm{CHO},-\mathrm{SO}{3} \mathrm{H},-\mathrm{COR}$
(4) $-\mathrm{CN},-\mathrm{CHO},-\mathrm{NHCOCH}_{3},-\mathrm{COOR}$
Show Answer
Answer (3)
Solution
Formula: Mesomeric effect
All are $-\mathrm{M}$, Hence meta directing groups.
