Quick Summary

A secondary alcohol is a chemical compound characterized by a carbon atom bonded to a hydroxyl group (>CHOH), one hydrogen atom, and two other carbon atoms. This structure means the carbon atom holding the hydroxyl group is itself attached to two other carbon atoms.1

Secondary alcohols can be oxidized to form ketones. Unlike primary alcohols, which can be further oxidized to carboxylic acids, secondary alcohols are oxidized only to the ketone stage without breaking carbon-carbon bonds. This property makes them valuable intermediates in organic synthesis. Alcohols are classified as primary, secondary, or tertiary based on the number of carbon atoms attached to the carbon bearing the hydroxyl group.2345

Reactions of ketones
Secondary alcohols are easily oxidized to ketones (R₂CHOH → R₂CO). The reaction can be halted at the ketone stage because ketones are generally resistant to further oxidation. Oxidation of a secondary alcohol to a ketone can be accomplished by many oxidizing agents, most often chromic acid…

Structure and classification of alcohols
A secondary alcohol has the hydroxyl group on a secondary (2°) carbon atom, which is bonded to two other carbon atoms. Similarly, a tertiary alcohol has the hydroxyl group on a tertiary (3°) carbon atom, which is bonded to three other carbons. Alcohols are referred to…
