Student X was investigating the reaction between S-2-bromopentane and sodium iodide in acetone in order to establish whether the nucleophilic substitution proceeds via the SN1 or the SN2 mechanism. IN addition to the chemicals and glassware the student has access to a polarimeter.
A. What physical property would the student measure to determine SN1 or Sn2 nature of the reaction?
B. What would the student observe if the reaction proceded via SN1 reaction?
C. What would the student observe if the reaction proceded via SN2 reaction?
