Question

What is friedel craft alkylation reaction? Discuss its limitations.

Answer 1

An alkyl group can be added to a benzene molecule by an electrophile aromatic substitution reaction. One example is the addition of a methyl group to a benzene ring. The mechanism for this reaction begins with the generation of a methyl carbocation from methyl bromide.

LIMITATIONS :

Aniline do not undergo friedel crafts reactions

Benzoic acid does not give Friedel Craft reaction

Pyridine does not give Friedel Craft reaction
