Unformatted text preview: (a) δ 0.00 (4 H) δ 7.60 (10 H) (b) δ 5.35 (12 H), δ 10.56 (4 H) (c) δ-4.25 (6 H), δ 8.14-8.67 (10 H) (d) δ-3.0 (6 H), δ 9.0 (12 H) Match each spectrum with each structure. CH 3 CH 3 A B C D H H H H 5. 3-Chlorocyclopropene, on treatment with AgBF 4 , gives a precipitate of AgCl and a stable solution of a product that shows a single 1 H NMR absorption at δ 11.04. Propose a plausible structure for the product and explain its stability. Cl H 6. (a) Azulene, an isomer of naphthalene, has a large dipole moment ( μ = 1.0 D). Explain. (b) Indole is an aromatic heterocycle that has a benzene ring fused to a pyrrole ring. Draw an orbital picture of indole. N H...
