Question 4 1.5 pts What major product forms from the following E2 elimination reaction? CH3 Br excess KOH ethanol, heat CH3 Hints: (1) Please be sure you understand where the possible anti-periplanar eliminations can occur for this substituted cyclohexane. Therefore, it is recommended that you convert the starting alkyl halide into its chair structural representation. (2) The ring beta-proton should be trans to the alpha-halogen leaving group in...

The tosylate of (2R, 3R)-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 me wedged or hashed bonds on it. Predict the major alkene product of the following E1 reaction: Amines are converted into alkene5, by a two-step process called the Hofmann elimination. S_N 2...
