D Question 1 1 pts For poly-substituted benzene rings, the site(s) of EAS can often be predicted by considering directing effects of the substituents, relative activating ability of substituents, and steric effects. Answer the questions about EAS of the poly-substituted benzene below. CH3 Br ÓCH3 The methyl group directs addition to positions[Select ] The bromine group directs addition to position(s) Select] The methoxy group directs addition to position(s)[Select] EAS will occur at positions) Select]Explanation / Answer
In general electron donating groups are ortho/para directing (2/4 wrt to that group) and electron withdrawing groups are meta (3) directing. In case of halogens although they are electron withdrawing, due to the presence of lonepair it donates that to the aromatic ring. Here all the groups are ortho/para directing.
Based on methyl the incoming group will go to a,c.
Based on Br its only c.
Based on OMe its only c.
Thus by considering all, the incoming group will go to the position c.
