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.
