Extent of Hydration

ORGO2-JRUYQR

When ketones and aldehydes are placed in an aqueous environment they form hydrates, or 1,1-diols. Although this equilibrium usually favors the ketone form, the hydrate must be considered as a potential part of any mechanistic scenario where water is part of the reaction mixture. The equation for hydration is depicted below.
