Indicate the approximate pka's for the Bronsted dissociation of the proton in boldface in the following molecules (write your answers in the appropriate boxes) C N Br C 3 C C S 2 CF 3 C 3 C (15 pts.) Write a detailed mechanism to account for the observation that treatment of compound A with ozone, but without the usual Zn/ + step, furnishes a 1 : 1 mixture of products B and C: 3 no Zn / + + A B C 1 : 1 ratio + ± + ± + B C
3 Chem 203 final exam p. 3 of (24 pts.) Draw: a. Accurate mechanisms for an example of S N 2 reaction and an example of S N 1 reaction: S N 2: Br N 3 + Br N 3 S N 1: Cl C 3 (or other C 3 Cl C 3 ± + C 3 polar solvent) b. A chemical equation showing an example of Williamson reaction (without mechanism): Na C 3 I C 3 c. A chemical equation showing an example of Wittig reaction (without mechanism): Ph 3 P=C 2
4 Chem 203 final exam p. 4 of 15 d. A chiral Schiff base: N e. An achiral epoxide that will react with aq. 2 S 4 to form a chiral diol: f. An olefin containing at least than 3 C atoms that will produce the same diol when treated either with s 4 followed by aq. NaS 3, or with MCPBA followed by aq. 2 S 4. g. An alcohol containing at least 4 C atoms that is likely to undergo dehydration without rearrangement and one also containing at least 4 C atoms that is likely to undergo rearrangement during dehydration (write your answers in the appropriate boxes): not likely to rearrange likely to rearrange h. An alcohol that forms the same product when treated either with PCC or with the Jones reagent, and one that forms one product when treated with PCC, but a different product when treated with the Jones reagent (write your answers in the appropriate boxes): gives the same product gives two different products
5 Chem 203 final exam p. 5 of (35 pts.) The 1 NMR spectrum of an alkane, A, exhibited only a singlet at 0.9 ppm. Treatment of A with Cl 2 / hv afforded a monochloro derivative, B, which upon reaction with metallic Mg followed by formaldehyde, -C, produced compound C. The IR spectrum of C displayed a strong, broad absorption at 3340 cm 1. The 1 NMR spectrum of C is shown below. Reaction of C with 2 S 4 at 160 C yielded compound D. When substance D was treated with s 4 followed by aqueous NaS 3, compound E emerged. Furthermore, ozonolysis of D followed by Zn/ + produced only F, which upon treatment with NaB 4 furnished G. The 1 NMR spectra of E and G are also provided below. Deduce the structures of compounds A G and write your answers in the appropriate boxes. s 4, then E A Cl 2 hv B 1. Mg 2. C C 2 S C D aq.
