Question

What happens when glucose reacts with bromine water? Write the chemical equation.

Hint:

Glucose is oxidized to gluconic acid in the presence of bromine water, and this reaction is a typical oxidation of the aldehyde group in sugars.

Answer 1

When glucose (C$_6$H$_{12}$O$_6$) reacts with bromine water, the bromine (Br$_2$) oxidizes the glucose, particularly the aldehyde group. The reaction results in the formation of a carboxylic acid (gluconic acid). The balanced chemical equation for this reaction is:

Here, glucose is oxidized to gluconic acid, and bromine is reduced to bromide ion.
