Determine the mechanism for both reactions

Assignment Help Chemistry
Reference no: EM131344413

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 SN1 or SN2 mechanism.  To determine the mechanism for both reactions, the student increased the concentration of the nucleophile in reactions A and B.  The rate of reaction for reaction A increased.  The rate of reaction for reaction B remained the same.

(a) Which reaction is the SN1 reaction?

(b) Which reaction is the SN2 reaction?

(c) Explain both choices.
