- The following alcohols react with HBr to afford an alkyl bromide. Based on their structures, indicate if the reaction mechanism is likely to be Sn1 or Sn2Acetic anhydride reacts with water in the following manner: CH3C(O)-O-C(O)CH3 + H2O = 2CH3CO2 If this reaction is carried out in an inert solvent with low concentrations of both acetic anhydride and water, it follows the rate law rate = k [CH3C(O)-O-C(O)CH3] [H2O] with a rate constant of 0.0035 s-1. However, if low concentrations of acetic anhydride are placed in pure water, it follows the rate law rate = K [CH3C(O)-O-C(O)CH3] where K = 0.1944 s-1.
