Alcohol Oxidation Free radicals Secondary alcohol gets easily oxidized to ketone but further oxidation is not possible. These initiation steps generate macroradicals at tertiary sites, as these are more stabilised. Hence, the oxygen can get protonated and leave as a water molecule, giving rise to a tertiary carbocation.
Primary alcohols can be oxidized to form aldehydes and carboxylic acids; secondary alcohols can be oxidized to give ketones. The following are examples of amino acid side chains that form hydrogen bonds. alcohol Oxidation of Tertiary Alcohols Since the carbon atom that holds the OH group does not have Secondary alcohols are converted to the corresponding ketone.
