Draw the energy diagram of the following reaction (label and draw reactants, intermediates, and products). Label transition state of the rate limiting step and draw the transition state of the rate determining step. Is it a concerted or stepwise reaction? Write the rate law for this reaction. How do we increase the reaction rate? If we use deutrium-tert-butyl bromide such as (CD3)3CBr instead of (CH3)3CBr, will it increase or decrease the reaction rate? Or there is no meaningful rate change. Write reasons for your answer. Draw mechanisms for reactions by drawing arrows and intermediates.
