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.
