Q. Which of the following compounds will not undergo Friedel-Crafts reaction easily?
A) Cumene
B) Xylene
C) Nitrobenzene
D) Toluene
Explanation
[Solution from source] The –NO₂ group strongly deactivates the ring and also complexes with AlCl₃, so nitrobenzene does not undergo Friedel–Crafts reactions easily. Cumene, xylene and toluene have activating alkyl groups and react readily. Answer (3).
