The resonance forms for the purple anion obtained by the reaction of ninhydrin with α-amino acid are to be given. Concept introduction: The resonance forms differ only in the position of the π bonds or the unshared pair of electrons on atoms. The position of atoms remains the same in different forms. The total number of valence electrons in all the resonance structures remains the same. Octet rule is not violated and the transfer of electrons between the bonds is indicated by curved arrows. To give: The resonance forms for the purple anion obtained by the reaction of ninhydrin with α-amino acid.
