Oxidation of alcohols. A strong oxidizing agent (potassium dichromate, K2Cr2O7, yellow) has been added to three alcohols. A reaction has occurred with the primary and secondary alcohols (left & centre). The tertiary alcohol (right) has not reacted. A primary or secondary alcohol has a hydroxyl group (-OH) attached to a carbon atom joined to two or one hydrogen atoms respectively. A tertiary alcohol has a hydroxyl group attached to a carbon with no hydrogen atoms.
