Reference: OCR
The hydrogen attached to the carbonyl carbon allows the aldehyde to be oxidised to a carboxylic acid, while the ketone resists this oxidation under the same mild conditions.
Tollens’ reagent is a mild oxidising agent that is reduced by an aldehyde when the unknown is warmed with freshly prepared reagent in a clean test tube.
Aldehydes are readily oxidised to carboxylic acids, with an oxygen inserted into the C–H bond of the carbonyl carbon.
The aldehyde is oxidised to the corresponding carboxylate when warmed gently with Tollens' reagent.
An aldehyde is oxidised to a carboxylic acid, turning the solution from orange to green.
