- Abstract
Kinetics of oxidation of some aldoses viz. D- ribose, D- xylose, L - arabinose and D- glucose by N- bromosaccharin in aqueous acetic medium in the presence of mercuric acetate as a scavenger for Br-, exhibits first order dependence in [NBSA] and [HC1O4]. The order with respect to aldose varies from 1 to 0. The reaction rate is retarded by the addition of saccharin. Effect of variation of composition of acetic acid-water binary mixture was also studied. Various activation parameters have been computed. These results points to a polar mechanism involving the formation of hypobromite ester in pre- equilibrium step which disproportionates into products via rate limiting attack of water molecule.
