Hydrolysis of the sucrose with dilute aqueous sulphuric acid yields.

Options

A. 1:1D-(+)-glucose, D-(-)fructose
B. 1:2D-(+)-glucose, D-(-)-fructose
C. 1:1D-(-)-glucose, D-(+)-fructose
D. 1:2D-(-)-glucose, D-(+)-fructose

Answer

A

Explanation

Hydrolysis of sucose with dilute aqueous sulphuric acid gives a equimolar mixture of D-(+) glucose and D-(-)- fructose
The reaction is
`C_12H_22O_11+H_2Ooverset(H_(2)SO(dil.))toC_6H_12O_6+C_6H_12O_6
:.1:1D-(+)-"glucose" D-(-)-f"ructose" D-(+)-"glucose",D-(-)"-fructose"`
