B) $ CN $
C) $ COCH_3 $
D) $ NHCOCH_3 $
Show Answer
Answer:
Correct Answer: D
Solution:
-COOH and $ COCH_3 $ are meta directing group due to the presence of $ -\overset{O}{\mathop{\overset{||}{\mathop{C}}}}- $ , similarly CN is also meta directing due to the presence of multiple bond while $ NHCOCH_3 $ is ortho/para directing group because of less electron density over $ -\overset{O}{\mathop{\overset{||}{\mathop{C}}}}- $ group.
