- Please provide the mechanism!! The tautomer that predominates in aqueous Solution? A. Enol form B. Keto formarrow_forwardProvide the missing reagent(s) needed to complete the following reactions. For each reaction determine whether the mechanism went through a carbocation, a 3-membered ring intermediate, or was concerted. Also indicate whether the reaction follows Markovnikov’s Rule, and is syn or anti addition.arrow_forwardDraw a detailed step-wise mechanism for the following reactions.
