Methoxy benzene (anisole) reacts with a mixture of FeBr3 and Br2 and the major products obtained are ortho- and para-substituted. Draw the 3 major and minor products of the reaction and use resonance structures of the carbocation intermediate to explain why ortho and para substitution occur in preference to the meta-substitution.

(V) 10pts. When aniline (C6H3-NH2) reacts with bromonium ion (NO2. the nitro group can become bonded to a carbon at one of the three possible positions: ortho, meta, and para to the -NH2 group in the benzene ring. Consider meta and ortho attack and draw RESONANCE STRUCTURES for the carbocations that result when NO2 undergoes electrophilic aromatic substitution to aniline. Then, on the basis of these resonance structures, explain whether the --NH2, group.is meta director, or ortho/para director. Show which...
