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.
