Bromine water

Vedclass · Answer

(C) When glucose is treated with bromine water ($Br_2$ water),it undergoes mild oxidation to form gluconic acid. In this reaction,the aldehydic group $(-CHO)$ is selectively oxidized to a carboxylic acid group $(-COOH)$,while the secondary alcoholic groups remain unaffected. This reaction confirms that the carbonyl group in glucose is an aldehydic group. The reaction is: $CHO(CHOH)_4CH_2OH + [O] \xrightarrow{Br_2/H_2O} COOH(CHOH)_4CH_2OH$ (Glucose $\rightarrow$ Gluconic acid)

Which reagent among the following is used to confirm the presence of an aldehydic carbonyl group in glucose?
