Question

Which of the following statement is correct regarding the nature and directive influence of \( \text{NO}_2 \) group in nitrobenzene?

• A. It is an activating group and ortho/para director
• B. It is a deactivating group and ortho/para director
• C. It is a deactivating group and meta director
• D. It is an activating group and meta director

Hint:

Electron-withdrawing groups like \( \text{NO}_2 \) deactivates the ring and direct electrophiles to the meta position.

Answer 1

The Correct Option is C

Step 1: Nature of \( \text{NO}_2 \) group.
The \( \text{NO}_2 \) group is an electron-withdrawing group, which deactivates the benzene ring and makes it less reactive towards electrophilic substitution reactions. Step 2: Directive influence of \( \text{NO}_2 \).
The \( \text{NO}_2 \) group directs incoming electrophiles to the meta position, as it deactivates the ortho and para positions due to its electron-withdrawing nature. Step 3: Conclusion.
Thus, the correct answer is that \( \text{NO}_2 \) is a deactivating group and a meta director. Final Answer: \[ \boxed{\text{It is a deactivating group and meta director}} \]
