Objective: To study the E2 dehydrohalogenation reactions of alkyl halides. In the reaction you will be performing, 3-chloro-3,7-dimethyloctane is a 3° halide, so the rate of substitution will be very slow (strongly favoring E2 elimination). Elimination is also favored over substitution when a strongly basic and only slightly polarizable ...
