The tosylate of (2S, 3S)-3-phenylbutan-2-ol undergoes an E2 elimination on treatment with sodium ethoxide. Draw the structure of the alkene that is produced. Use the wedge/hash bond tools to indicate stereochemistry. You do not have to explicitly draw H atoms. If a group is achiral, do not use wedged or hashed bonds on it.

Following are two diastereomers of 3-bromo-3, 4-dimethylhexane. On treatment with sodium ethoxide in ethanol, each gives 3, 4-dimethyl-3-hexene as the major product. One diastereomer gives the E alkene, and the other gives the Z alkene. Which diastereomer gives the E alkene? Following are two diastereomers of 3-bromo-2, 3, 4-trimethylhexane. On treatment with sodium ethoxide in ethanol, each gives 23, 4-trimethyl-3-hexene as the major product. One diastereomer gives the E alkene, and the other gives the Z alkene. Which diastereomer gives...
