Question

Give the organic product: HN H,50 +HNO 0 IV Select one: C. IV Which of the following is a limitation of the Friedel-Crafts reaction? Select one: A. The carbocation electrophle can potentially undergo an unwanted rearrangement prior to its bonding to the aromatic ring. B. Poly-alkylation products form when aromatic reactant and alkylating agent are mixed together in comparable amounts. C. A Friedel-Crafts reaction fails when the aromatic starting compound contains a moderately or strongly deactivating group. D. All of the above choices are limitations of the Friedel-Crafts reaction. Which of the following is the electrophile in the sulfonation of benzene? Select one: A (SO2-H20) B. SO2 C. SO3H D. (O2N-So3)+

Explanation / Answer

Option A, product I. Since NHCOCH3 is good o/p directing group than CH3. Hence nitration occurs at ortho to NHCOCH3 instead of para substitution since Para position is occupied by CH3 group.

All statements are correct, limitations of Friedal crafts alkylation.

Option C, SO3H+ , is the electrophile during sulfonation of benzene.
