Vedclass · Answer

(B) The hydrolysis of sucrose $(C_{12}H_{22}O_{11})$ in the presence of dilute acid yields glucose $(A)$ and fructose $(B)$.$C_{12}H_{22}O_{11} + H_{2}O \xrightarrow{H^{+}} C_{6}H_{12}O_{6} (	ext{Glucose}) + C_{6}H_{12}O_{6} (	ext{Fructose})$Glucose $(A)$ on oxidation with $HNO_{3}$ gives saccharic acid (glucaric acid).Fructose $(B)$ is a laevorotatory sugar $([\alpha] = -92.4^{\circ})$.Thus,the sugar $X$ is sucrose.

When sugar $X$ is boiled with dilute $H_{2}SO_{4}$ in an alcoholic solution,two isomers $A$ and $B$ are formed. $A$ on oxidation with $HNO_{3}$ yields saccharic acid,whereas $B$ is laevorotatory. The compound $X$ is ....... .
