Reacting (2R)−2−pentanol with HBr leads to the formation of equal amounts of (2R)−2−bromopentane and (2S)−2−bromopentane. Draw a stepwise mechanism for the reaction that is consistent with this observation.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
