Part A In the acid-base mechanism, the base is a proton acceptor, and the acid is the proton donor. An acid-base reaction is visualized as the reaction in which proton transfer takes place. However, in a nucleophilic substitution reaction, the nucleophile attacks a substrate (usually an electrophile), and the leaving group is removed from the substrate as a weaker nucleophile. The nature of the reactants determines whether a reaction will proceed as an acid-base reaction or a nucleophilic substitution reaction....

2-Bromo-2-methylbutane undergoes an E1 elimination reaction in
the presence of ethanol. In the next reaction only one of the
possible products is represented. Although the product shown is not
the major product of the reaction, notice that there is more than
one way it can be produced. Complete the mechanism and draw the
missing substances.
Draw all missing reactants and/or products in the appropriate
boxes by placing atoms on the grid and connecting them with bonds,
including charges where needed....
