Glucose on oxidation with bromine water yields gluconic acid. This reaction confirms the presence of -

Options

ASix carbon atoms linked in straight chain
BSecondary alcoholic group in glucose
CAldehyde group in glucose
DPrimary alcoholic in glucose

Correct answer

C. Aldehyde group in glucose

Step-by-step solution

Glucose on oxidation with bromine water yields gluconic acid. This reaction confirms the presence of aldehyde group. Because for the formation of gluconic acid, free aldehyde group must be present.
