Detection of foreign elements in organic compounds

FOREIGN ELEMENTS:Other elements rather than carbon and hydrogen present in organic compounds are called foreign elements.e.g. NH2-C-NH2 , ---Cl . here Nitrogen(N), Chlorine(Cl) are foreign el...

Define: a. Perkin's condensationb. Aldol condensationc. Cannizaro reactiond. Benzoin condensation e. Wolf Kishner reactionf. Carbylamine reaction

a. Perkin's condensation:The reaction between an aromatic aldehyde and the anhydride of an aliphatic acid in the presence of sodium salt of the same acid, leading to the formation of an alpha, beta unsaturated acid is called Perkin's reaction. For example, benzaldehyde and acetic anhydride give cinnamic acid.

benzaldehyde + acetic anhydride --CH₃COONA (455K)----> Cinnamic acid + CH₃COOH

b. Aldol Condensation:Aldehydes and Ketones having at least one alpha-hydrogen atom in the presence of...
