Question
Predict all the alkenes that would be formed by dihydrohalogenation of the following halides with sodium ethoxide in ethanol and identify the major alkene:
1-bromo-1 methyl cyclohexane.
Solution
In the 1-bromo-1-methylcyclohexane, all b -hydrogen atom are equivalent. Thus, dehydrohalogenation of this compound gives only one alkene as follows:
