why cant n-proplybenzene be synthesized by Friedel-Crafts alkylation reaction?
Homework Answers
Because n-propylbromide on heterolytric cleavage gives n-propyl carbocation, which invloves in rearrangement so that isopropyl carbocation generation takes place. so that on alkylation it gives only cumene as major product but n-proplybenzene is a minor product.

When performing a Friedel-Crafts alkylation reaction, not only does one have the problems of multiple alkylation and rearrangement of the cation, but the presence of strong electron donating groups(yes, donating is correct) prevents reaction. Provide an explanation for this. Metallocenes, like ferrocene cannot be nitrated. Why? Draw the structure of the diacetylferrocene you would obtain if ferrocene were diacetylated. Draw an arrow pushing mechanism for the formation of the acylium ion when acetic anhydride reacts with phosphoric acid. Provide the...
