H „CH3 LCH, (a) (R)-1,2-propanediol (b) (S)-1,2-propanediol

A ketone undergoes acid-catalyzed bromination, acid-catalyzed chlorination, racemization, and acid-catalyzed deuterium exchange at the α-carbon. All of these reactions have similar rate constants. What does this tell you about the mechanisms of these reactions?
