4. Fill-in-the-blanks: draw the missing reactants or products involved in the following single or multi-step reactions. Indicate stereochemistry and draw multiple stereoisomers where applicable. i EtOH EtOH [H2SO4] 1) EtMgBr 2) H20 5. For most ketones, hydrate formation is unfavorable, because the equilibrium favors the ketone rather than the hydrate. However, the equilibrium for hydration of hexafluoroacetone favors the hydrate. Propose a mechanism for this transformation below and provide an explanation for this observation. H2O Но он F3CX CF3 F3C...
