D − glucose → Tollen ′ s reagent A ; D − glucose → Br 2 -water B A and B are:

Options

Agluconic acid, gluconic acid
Bglucaric acid, gluconic acid
Csalt of gluconic acid, gluconic acid
Dsalt of gluconic acid, glucaric acid

Correct answer

C. salt of gluconic acid, gluconic acid

Step-by-step solution

Tollen's reagent is a mild oxidising agent and easily oxidises the aldehyde group, but can not oxidise the ketone or alcohol group and form salt of gluconic acid. B r 2 / H 2 O is a mild oxidising agent and easily oxidises the aldehyde group, but cannot oxidise the ketone or alcohol group.
