Question

How many of the following will produce gluconic acid or it's salt when treated with D- Glucose (a) Tollen's reagent (b) HNO3 (c) Br2/ water (d) HIO4 (e) Fehling's solution (f) Red P/HI/Δ (g) Benedict's solution (h) PhNHNH2 (i) HCN (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

D-glucose oxidised to gluconic acid by reacting with Tollen's reagent,

B r_{2}

/ water, benedict's solution and fehling's solution.
On reacting with nitric acid, which is a strong oxidising agent, D-glucose convert into saccharic acid, which is dicarboxylic acid.
On reacting with Red

P / H I /Δ

, which is a strong reducing agent, D-glucose convert into n-hexane.

P h N H N H_{2}

form hydrazine by reacting with aldehyde group of D-glucose.

H CN

form cyanohydrin with glucose.

H I O_{4}

on reacting glucose form formic acid and formaldehyde.
