Question

Question 1 Identify all compounds below that CANNOT be made by the electrophilic aromatic substitution reactions introduced in Sections 18.1-18.6 SOH Question 2. Match each pair of structures with the appropriate term. KEY 1 = Constitutional isomers 2 - Diastereomers 0 000 3 = Different conformations 4 = Resonance structures 5 = Bond-shift isomers

Answer 1

sulfonation (electrophile = #303H), Nitaution (electrophile - Noz), Friedel Grafts alkylation (electrophile - CH₂ C=0) are example of electo philic asomatic substitution.

D also com be made by using Fe Boz / Br2 But preparation of anisole (E) and iodo benzene (A) are not prepared by electrophilic assmatic substitu - tion. Ans: A E

A. B. c. D. Dia stereomes. Different conformation. Constitutional isomess. Dia stereomes. 3. Here Felbro act as lewis acid and complex is electrophile which gives Bot. 4. Cis-diene readily giver dieks - alder seaction. Normally does not act as di-ene. More accurentely, (Don't show)
