In order to convert a ketone into alcohol, the correct option has to be chosen from the given oxidizing and reducing agents. Concept Introduction: In organic chemistry , oxidation reaction is referred to the number C − O bonds increase and/or number of C − H bonds decrease. In organic chemistry, reduction reaction is referred to the number C − O bonds decrease and/or number of C − H bonds increase. Alcohols undergo oxidation reaction and reduction reaction. This depends upon the number of hydrogen atoms that is bonded to the alpha carbon atom. Primary and secondary alcohol undergoes oxidation reaction while tertiary alcohol does not undergo oxidation reaction. Primary alcohols undergo oxidation to give aldehyde and carboxylic acid as product. Secondary alcohol undergoes oxidation to give ketone as the product. Aldehyde undergoes oxidation to give carboxylic acid as the product while ketone does not undergo oxidation reaction. The reverse of oxidation reaction is reduction reaction. Reduction of aldehyde gives primary alcohol as the product and reduction of ketone gives secondary alcohol as the product. Reduction can be accomplished using hydrogen gas and a metal catalyst namely nickel.
