Which of the following is true of SN1 reactions? a. They are stereospecific. b. They occur in a single step. c. They are second order. d. They proceed through a carbocation intermediate. e. Their rate is dependent on the concentration of attacking nucleophile. Which statement corresponds to an SN2 reaction? a. They occur in two steps. b. The rate aw is: rate = k[R-L][nuc] c. Stabilization of the carbocation (R^+) is important. d. They lead to a mixture of configurations at a chiral carbon. e. They are favored by protic solvents.Explanation / Answer
4.
