Q. Which of the following reactions establish difference between glucose and fructose?

Tollen’s reagent reaction

Phenyl hydrazine

$P / H I$

cone. $H N O_{3}$

Glucose $co n c . H N O_{3} COO H - (C H O H)_{4} - COO H$

Fructose $co n c . H N O_{3} H OOC - (C H O H)_{2} - COO H + H OC H_{2} - COO H$

Q. Which of the following reactions establish difference between glucose and fructose?

Tollen’s reagent reaction

Phenyl hydrazine

P/HI

cone. HNO3​

Glucose conc.HNO3​​COOH−(CHOH)4​−COOH Fructose conc.HNO3​​HOOC−(CHOH)2​−COOH+HOCH2​−COOH

$P / H I$

cone. $H N O_{3}$

Glucose $co n c . H N O_{3} COO H - (C H O H)_{4} - COO H$

Fructose $co n c . H N O_{3} H OOC - (C H O H)_{2} - COO H + H OC H_{2} - COO H$
