Which of the following does NOT undergo Friedel-Crafts alkylation with CHX3Cl and anhydrous AlClX3?
AToluene
BAnisole
CNitrobenzene
DChlorobenzene
Answer: C
The nitro group strongly deactivates the ring and also complexes with AlClX3, so the ring is too electron-poor to attack the electrophile. Chlorobenzene is deactivated only weakly and does react.
