Unformatted text preview: Plot amount of tert-butyl bromide on the x-axis and average time on the y-axis. 5. A student ran two separate substitution reactions, Reaction A and Reaction B, in lab that utilized an alkyl halide and a nucleophile. However, he did not know if the reactions proceeded through an S N 1 or S N 2 mechanism. To determine the mechanism for both reactions, the student decreased the concentration of the Chem 2545 Fall 2007 nucleophile in Reactions A and B. The rate of reaction for Reaction A decreased. The rate of reaction for Reaction B remained the same. a) Which reaction is the S N 1 reaction? (b) Which reaction is the S N 2 reaction? (c) Explain both of your choices. 6. Unlike the S N 2 reaction, a nucleophile is less impeded by steric hindrance in a S N 1 reaction. Explain....
