Write the mechanisms for each of the reactions below. Label each step of the reaction according to its type of elementary step $($arrow pushing pattern$).$ Then label each molecule in each step as a nucleophile, acid, base, leaving group, or electrophile. If two types of patterns are observed in the same step $($a concerted reaction$),$ label with both.
