Final Exam Questions, Experiment 5 A multistep synthesis of aniline from toluene is shown below, with reagents missing. Use it to answer the following questions. 1) Which reagents would you use to perform reaction A? a) KMnO b) N-bromosuccinimide, UV light. c) NaOH. d) OsO.. 2) Which reagents would you use to perform reaction B? a) PBr. b) p-toluenesulfonyl chloride. c) SOCI2. d) NaOCl, NaOH. 3) Which reagents would you use to perform reaction D? a) NaN3, heat. b) NH3. c) KOH d) Brz, KOH. 4) You're performing your Hofmann rearrangement, and you misplace your bottle of bleach. What could you use as a substitute that would still give good yield? a) Sodium azide. b) NaOH. c) Bromine. d) Hydrogen peroxide. 5) Why did you add NaHSO, at the end of your Hofmann rearrangement? a) To make the reaction mixture aqueous, not organic. b) To neutralize the acidic solution before extraction of product. c) To neutralize the basic solution before extraction of product. d) To destroy any leftover bleach in the reaction. 6) The NMR spectrum of 3-nitroaniline was taken in deuterated dimethylsulfoxide (DMSO), not CDCiz. Why? a) The residual CHCI peak would get in the way of the aromatic peaks in the product. b) 3-Nitroaniline is not soluble in CDCls. c) DMSO allows visualization of the peaks for the NH2 group. d) 3-Nitrobenzamide is not soluble in CDC13.

    Page 1 Synthesis using Carbonyl O-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the organic starting material (what you have to work backwards toward) depends...
