QUESTION TEN a) The Hammett plot for hydrolysis of the acid chlorides of benzoic acids in aqueous acetone is very odd indeed. Hammett plots need not be perfectly linear to give useful information, but this one is clearly made up of two intersecting straight lines. Explain the observed Hammett $\rho$ values. $H_2O$ Ar Cl Ar OH acetone $\log\ k$ $ArCOCl$ hydrolysis $\rho = -4.4$ $\rho - Cl$ $\rho = +2.5$ b) Consider the following Hammett plots for the given reaction. Provide a detailed reaction mechanism to account for the observed Hammett $\rho$ values. $H_2SO_4$ $H_2O, HOAc$ OH $\rho = +2.67$ $\rho = -2.51$
