Current Question (ID: 21281)

Question:

$\text{Identify correct statement(s):}$ $\begin{array}{ll} (A) & -\text{OCH}_3 \text{ and } -\text{NHCOCH}_3 \text{ are activating groups.} \\ (B) & -\text{CN and } -\text{OH are meta-directing groups.} \\ (C) & -\text{CN and } -\text{SO}_3\text{H are meta-directing groups.} \\ (D) & \text{Activating groups act as ortho- and para-directing groups.} \\ (E) & \text{Halides are activating groups.} \end{array}$ $\text{Choose the correct answer from the options given below:}$

Options:

1. $(A), (C) \text{ and } (D) \text{ only}$
2. $(A), (B) \text{ and } (E) \text{ only}$
3. $(A) \text{ only}$
4. $(A) \text{ and } (C) \text{ only}$

Solution:

$(B) -\text{CN is meta directing but } -\text{OH is ortho/para directing. \newline (E) \text{ Halides are deactivating groups.}$
