18. Reactions of Aromatics:EAS and Beyond - Part 2 of 3

19. Reactions of Aromatics: EAS and Beyond / Limitations of Friedel-Crafts Alkyation / Problem 8

Friedel–Crafts alkylation suffers from overalkylation.
i. Identify the product of the reaction below considering overalkylation
ii. What makes it difficult to control and add only one alkyl group?

A

ii. Alkyl groups are small enough to simultaneously react at multiple carbons in a benzene ring.

B

ii. Adding alkyl groups to benzene activates the ring and makes it more reactive, thus promoting more alkylation.

C

ii. Adding alkyl groups to benzene activates the ring and makes it more reactive, thus promoting more alkylation.

D

ii. Alkyl groups are small enough to simultaneously react at multiple carbons in a benzene ring.
