MCQ
The ortho/para directing group among the following is
- A$COOH$
- B$CN$
- C$COC{H_3}$
- ✓$NHCOC{H_3}$
✓
Answer
Correct option: D.
$NHCOC{H_3}$
d
(d) $-COOH$ and $COC{H_3}$ are meta directing group due to the presence of $ - \mathop {\mathop C\limits^{||} }\limits^O - $, 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 over $ - \mathop {\mathop C\limits^{||} }\limits^O - $ group.
