On hydrolysis with dilute aqueous sulphuric acid, sucrose forms a equimolar mixture of \(D-(+)\) -glucose and \(D-(-)\) -fructose. The reaction for the hydrolysis of sucrose is as follow

\(\mathop {{C_{12}}{H_{22}}{O_{11}}}\limits_{Sucrose}  + {H_2}O\xrightarrow{{{H_2}S{O_4}}}\mathop {{C_6}{H_{12}}{O_6}}\limits_{D - ( + ) - glu\cos e}  + \mathop {{C_6}{H_{12}}{O_6}}\limits_{D - ( - ) - fructose} \)

Solution of sucrose is dextrorotatory (specific rotation \(=+66.1^{\circ}\) ) but after hydrolysis gives dextrorotatory glucose and levorotatory fructose. The solution of formed product is found to be levorotatory (specific rotation \(\left.=-20.0^{\circ}\right)\)
