CHM 1321 Assignment #5 In this assignment: - S N 2 reactions - S N 1 reactions 1. Use arrow notation to show the mechanisms of the following reactions. Use your mechanism to predict the product of the reaction. Identify the nucleophile, its nucleophilic atom, the α carbon of the electrophile and the leaving group. 2. A solution of 0.25 M cyclohexylbromide and 0.36 M CH 3 NH 2 is created. Measurements show that the reaction produces 3.6 X 10 -7 mol L -1 of product each second. a) Calculate the rate constant for the reaction. b) If the concentration of CH 3 NH 2 is changed to 0.15 M, what is the initial rate of the reaction? c) Predict the relative rate (faster or slower) of the reaction if CH 3 CH 2 CH 2 OH is used in place of CH 3 NH 2 and justify your choice. d) What could be done to the electrophile to increase the rate of the reaction? Briefly explain your reasoning. e) Could cyclohexanol be used to produce the same product? Why or why not? If not, how could the reaction using cyclohexanol be altered to make it work?
