Question #168637
Compare the mechanisms for the following substitution and addition reactions of benzene:
o the Friedel-Crafts reaction
o the sulfonation of benzene
o the chlorination of benzene
o the hydrogenation benzene
You will need to illustrate and explain the reaction mechanism for each one, as well as the similarities and differences that exist between them.
Expert's answer
The Friedel-Crafts reaction
The sulfonation of benzene
The chlorination of benzene
Above all are Electophilic aromatic substitution reaction and carbocation is as a intermediate which is formed by electrophilic atrack over benzene ring .
In hydrogenation reaction H attachèd after removing Double bond through transition state .
