Summary
The rates of oxidation of several aromatic aldehydes with chromic acid have been measured using several mixtures of acetic acid and water as solvents. This study points to the fact that the oxidation proceeds by an iondipole mechanism. Evidence has also been obtained from these studies that the active oxidant is a cationic species, such as HCrO3/+ or H3CrO4/+. Amis’ equation for an ion-dipole reaction gives remarkably good values of ‘r’ thus confirming an ion-dipole mechanism.
