Glucose→ΔNaHCO3noreaction
Glucose→ΔHNO3saccharicacid
Glucose, on oxidation with nitric acid, gives saccharic acid.
Glucose→ΔHIn−hexane
Glucose, on prolonged heating with hot HI, gives n-Hexane.
Glucose→ΔBr2Gluconicacid
Glucose reacts with bromine water to form gluconic acid.
Bromine water is a mild oxidising agent which selectively oxidizes aldehyde to carboxylic acid only. It doesn’t oxidise alcohol or ketone.
Hence option B is the answer.
