15 But what is the order of bond making and bond breaking? In theory, there are two possibilities.  Bond making and bond breaking occur at the same time. This is an example of an S N 2 (substitution nucleophilic bimolecular) mechanism.
16  Bond breaking occurs before bond making. This is an example of an S N 1 (substitution nucleophilic unimolecular) mechanism.
Competition Between Substitution and Elimination Alkyl halides can undergo S N 2, S N 1, E2 and E1 1) decide whether the reaction conditions favor S N 2/E2 or S N 1/E1 S N 2/E2 reactions are favored by a high concentration of nucleophile/strong base S N 1/E1 reactions are favored by a poor nucleophile/weak base 2) decide how much of the product will be the substitution product and how much of the product will be the elimination product
