Question

4. Answer the following questions based on the electrophilic aromatic substitution reaction shown below. door a. (2.5pts) Based on the identity of the substituent on the starting material and its interaction with the aromatic ring, is this substituent an activator or deactivator? Briefly explain your answer and support your answer with structures b. (5.5pts) Draw all of the resonance contributors of the o-complexes that lead to each of the three possible products. c. (0.5p) Based on the structures drawn in part b, is this substituent an ortho para or meta directing substituent? No explanation required here, so parte d. (06) Considering ALL possible factors, which product would you choose as the MAJOR product ortho mellor para? No explanation required. ses part e. (3pts) Taking into account your answers for parts a-d draw the potential energy diagrams for each of the possible pathways. Reaction Coordinate 1. (Apts) Referring back to your potential energy diagram and your resonance structures, briefly explain the two choices you made in parts and

Answer 1

ॐex xx From the resonating structure of the substituent we can see it increases : eleefron density of benzene ring. So : it is a activator forom electrophilic a substitution reaction. Hat Alls to D ZI

Onane TO © As ortho and paria has extra stability by a group toan pair resonance. So, this substituent is an ontho/ para directing substituent. & The substituent is an artho/para .. direeting. But here a entra factor leo sterie hindarence predict the major : produet. As arthross sterie effect beth Een group and receity group, but- para product has no such sterie effect. So the major product of the reaction is para product. :
