WebAldehydes and ketones are reduced to alcohols with either lithium aluminum hydride, LiAlH 4, or sodium borohydride, NaBH 4. These reactions result in the net addition of the elements of H 2 across the CAO bond. As these examples illustrate, reduction of an aldehyde gives a primary alcohol, and reduction of a ketone gives a secondary alcohol. The oxidation of secondary alcohols to ketones is an important oxidation reaction in organic chemistry. When a secondary alcohol is oxidised, it is converted to a ketone. The hydrogen from the hydroxyl group is lost along with the hydrogen bonded to the carbon attached to oxygen. The remaining oxygen then forms double bonds with the carbon. This leaves a ketone, as R1–COR2. Ketones ar… WebModifications.
