Question

Predict the major organic product for given Friedel-Crafts alkylation reaction:

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

The Friedel-Crafts alkylation reaction is a method of generating alkylbenzenes by using alkyl halides as reactants in presence of $AlC{l}_3$
This is done through an electrophilic attack on the aromatic ring with the help of a carbocation. Here primary carbocation formed initally rearranges to a more stable secondary carbocation.
The Friedel-Crafts alkylation reaction of benzene is illustrated below.
