3. Write a mechanism for the following reaction for the two products. Justify the two products by assigning the proton NMR to the structures you provide. Hint: Consider the boldened proton environments carefully. Compound 1: 'H NMR ( 8/ppm) : 8.28 (1H, d), 7.77(1H,s),7.43 (1H, d), 3.91(3H,s),3.77(3H,s). Compound 2: 'H NMR ( /ppm):8.28 (1H, d), 7.96(1H,d),7.77(1H,s),4.02(3H,s),3.89(3H,s). [3] Reaction Mechanism (Please show appropriate resonance forms for attack on the electrophile, but not for restoration of aromaticity as there would be too many). Show generation of the nitronium electrophile
