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. HNO3/H2SO4 Compound 1: 1H NMR ( /ppm):8.28(1H,d),7.77(1H,s),7.43(1H,d),3.91(3H,s),3.77(3H,s). Compound 2: 1H NMR ( /ppm):8.28(1H,d),7.96(1H,d),7.77(1H,s),4.02(3H,s),3.89(3H,s)
