Question


--Consider the nitration of bromobenzene. The Br substituent of bromobenzene is ________ (activating, deactivating) and _______ (o/p, meta) directing.

--In the space below, draw the four most relevant resonance forms of the sigma-complex which would occur as an intermediate in the formation of para-bromonitrobenzene. (Do only consider this one-sigma complex here, do not consider the sigma complexes for the respective formations of ortho-or meta-bromonitrobenzene)

--Explain whether any of the resonance forms have any special advantage or disadvantage.

--State whether para-bromonitrobenzene will be formed.

Explanation / Answer

weakly deactivating , ortho para directing
