Hell Volhard Zelinsky Reaction Mechanism is quite different from other halogenation reactions as it takes place in the absence of a halogen carrier. The reaction is used for the halogenation of carboxylic acids at the alpha carbon. Fehling’s Solution: When formic acid is warmed with Fehling’s solution, a brick red ppt. of cuprous oxide is obtained. Acetone is oxidised by sodium hypoiodite, resulting in a yellow precipitate of iodoform and a sodium salt of acetic acid. The disproportionation of an aldehyde into a carboxylic acid and the corresponding alcohol in the Cannizaro reaction is base-catalyzed. Taking benzaldehyde as an example, the first step involves addition of a hydroxyl ion to the benzaldehyde. |
