1. Consider the following reaction: NaOH OH Br a. Draw the structure of the transition state for the rate determining step. (1 points) b. What is the rate equation? (1 points) c. What happens to the reaction rate in each of the following instances? (5 points) i) The leaving group is changed to i) The solvent is changed to water iii The alkyl halide is changed to CH3CH2CH20H2CH(Br)CH3 iv) The concentration of oH is decreased by a factor of two v The nucleophile is changed to CH30H. 2. MECHANISM: Using curved arrows to show the FLow oF ELECTRONS give the complete stepwise mechanism for the formation of the products in the following reaction. (4 points) N CH3 CH3NH3 Cl CH3NH2 excess)
