A mechanism for the formation of a purple-colored compound from ninhydrin has to be proposed. Concept introduction: Ninhydrin reacts with amino acid to form a purple-colored compound. The reaction is thus used to identify amines. It is a test given by all amino acids. Ninhydrin acts as an oxidizing agent and the product formed is a reduced form of ninhydrin, carbon dioxide, and an aldehyde .

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
