How will you differentiate between aldehyde ketone and carboxylic acid?
The carbonyl group, a carbon-oxygen double bond, is the key structure in these classes of organic molecules: Aldehydes contain at least one hydrogen atom attached to the carbonyl carbon atom, ketones contain two carbon groups attached to the carbonyl carbon atom, carboxylic acids contain a hydroxyl group attached to
In most academic courses you'd learn that aldehydes are more acidic (lower pKa) than ketones due to the lower electron donating effect of the proton compared to the alkyl group of the ketone.
The more acidic substance will be the one whose conjugate base is more stable.
What is the identification test for aldehyde ketone and carboxylic acid?
This test is known as the silver mirror test.
Aldehydes react by giving a grey-black precipitate or a silver mirror to the Tollens reagent.
A freshly prepared reagent from Tollen should always be used.
What are the important topics in aldehydes ketones and carboxylic acids?
The carbonyl group is one of the most important functional groups in organic chemistry because it contains a carbon-oxygen double bond (>C=O).
The carbonyl group is connected to a carbon and hydrogen in aldehydes, while it is bonded to two carbon atoms in ketones.
