In the Friedel-Crafts alkylation of benzene, why is it important to use excess benzene relative to the alkyl halide?
Options
- ATo increase the yield of alkylbenzene
- BTo reduce the reactivity of benzene
- CTo prevent the formation of side products
- DTo decrease the yield of alkylbenzene
Correct answer
C. To prevent the formation of side products
Step-by-step solution
Using excess benzene ensures that there is a sufficient amount of benzene to react with the electrophilic species and prevents the formation of side products by diluting the electrophile's reactivity.
