Consider the pair of reactions. Draw the organic products, then predict the type of substitution mechanism and compare the expected rates. Both reactions start with propyl chloride reacting with a halide ion in water to form a product. Reaction 1 has a bromide ion, while reaction 2 has an iodide ion. Draw product 1. Draw product 2. Identify the mechanism of each reaction. Reaction 1 occurs by an SN2 mechanism. Reaction 1 occurs by an SN1 mechanism. Reaction 2 occurs by an SN2 mechanism. Reaction 2 occurs by an SN1 mechanism. Compare the rates of each reaction. Reaction 2 is faster than reaction 1. Reaction 1 is faster than reaction 2. Both reactions occur at the same rate.
