The following substitution reaction is monitored by measuring the optical rotation of the solution as a function of time. Based on the results shown in the graph at the right determine whether the reaction takes place by a SN1 or Sn2 reaction pathway. Explain your reasoning. 10. А. +100- +50- NaBr 0- CH(Br)CHs -50- -100 Time
