... In conclusion, all steps included in the conversion of an aldehyde or ketone to acetal or ketal via hemiacetal or hemiketal as intermediates, are reversible. Performing the reaction in large excess of an anhydrous alcohol and a small amount of an anhydrous acid will strongly favour the formation of ...

Experiment 7-Reduction
... A reduction is often defined as the gain of two hydrogen atoms or the loss of an oxygen atom, or both. This leads to a very important conversion reaction, where aldehydes and ketones are reduced to primary and secondary alcohols. O ...
