Question

Which of the following has maximum laevorotatory nature ? (A) D-Glucose (B) D-Fructose (C) Sucrose (D) Invert sugar

Tardigrade Admin · Accepted Answer

D - ( + ) - glucose has specific rotation of + 52.5° D-(-)-fructose has specific rotation of - 92.4° while that of invert sugar has laevorotation of - 92-4° + 52 5° = -39.9°.

Q. Which of the following has maximum laevorotatory nature ?

$D$ -Glucose

$D$ -Fructose

Sucrose

Invert sugar

D - ( + ) - glucose has specific rotation of + 52.5 $^{\circ}$
D-(-)-fructose has specific rotation of - 92.4 $^{\circ}$
while that of invert sugar has laevorotation of - 92-4 $^{\circ}$ + 52 5 $^{\circ}$ = -39.9 $^{\circ}$ .
