Vedclass · Answer

(A) Sucrose undergoes hydrolysis in the presence of dilute aqueous sulphuric acid to produce an equimolar mixture of $D-(+)$-glucose and $D-(-)$-fructose. The chemical reaction is: $C_{12}H_{22}O_{11} + H_2O \xrightarrow{H_2SO_4} C_6H_{12}O_6 + C_6H_{12}O_6$ ($D-(+)$-glucose) ($D-(-)$-fructose) The molar ratio of the products is $1:1$. Sucrose is dextrorotatory,but the resulting mixture is laevorotatory because the specific rotation of $D-(-)$-fructose $(-92.4^{\circ})$ is greater in magnitude than that of $D-(+)$-glucose $(+52.7^{\circ})$.
