Given that glucose when treated with NaBH 4 gets reduced to yield sorbitol. How this reduction process occurs is to be shown. Concept introduction: The cyclic pyranose ring in glucose, when cleaved, will yield the open chain compound with a free aldehyde group. The aldehyde group can be reduced by NaBH 4 to an alcohol group to get sorbitol. To show: How the reduction of glucose by NaBH 4 to yield sorbitol occurs.

Question

a) Explain why product 1 is the kinetic product and product 2 is the thermodynamic product. b) Draw the reaction coordinate diagram for the reaction pathway generating each product. c) State the Arrhenius Equation and explain the terms with their physical significance. d) State and explain which reaction pathway has a higher rate constant. What happens to the rate constant if the temperature has increased?

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
