Question:

What is the mechanism of oxidation reaction of D-glucose with bromine water?

Answer:

The oxidation with bromine water undergoes as oxidation of cyclic form that is formed spontaneously according to the equation:

Next the elimination of HBr occurs. In addition, during this process lactone is formed. Lactone opens in the presence of water and OH $\cdot$ .

Also $\beta$ -D-glucopyranose undergoes oxidation faster than $\alpha$ -form due to the lower activation energy for the intermediate state.
