Predict the product of the following elimination reaction.

Elimination reactions can often give two different products, depending on which carbon atom
adjacent to the C−X bond is attacked. As a rule, the dominant product of the reactions is the most
highly substituted alkene. Predict the product of the following elimination reaction.

Assume that 2−bromopropane undergoes a combination of E2 and SN2 reactions when
it reacts with the CH3O− ion in methanol. Predict the products of the reactions.

17. Predict the most likely product or products of the following reactions.

18. Explain why the following reaction will not give the indicated product. Predict the product that
would form.

+ (CH3);CO Br
