Question

The ortho/para directing group among the following is

• A. $COOH$
• B. $CN$
• C. $COC{H}_3$
• D. $NHCOC{H}_3$

Answer 1

Answer: (D)

$-COOH$ and $COC{H}_3$ are meta directing group due to the presence of similarly $CN$ is also meta directing due to the presence of multiple bond while $NHCOC{H}_3$ is ortho/para directing group because of less electron density
