Write a mechanism for the formation of benzoic acid from acetophenone via the haloform reaction. Be as complete as possible and show electron flow for all steps. • Use Cl2 as the halogenating agent in your mechanism (you do not need to write a mechanism for the formation of Cl2 from NaOCI). WebCatalytic oxidation is a reaction with oxygen that occurs more rapidly and at a lower temperature in the presence of another substance (called a catalyst) than it would in the absence of the catalyst. The catalyst only speeds up the reaction. It doesn't get used up in the process. It can be used over and over again. sheppard east po
