उत्तर
Sucrose (cane sugar) is a disaccharide. One molecule of sucrose on hydrolysis gives 1 molecule of glucose + 1 molecule of fructose.
Explanation:
One of the common disaccharides is sucrose which on hydrolysis gives equimolar mixture of D – (+) – glucose and D – (–) – fructose.
\[\ce{C12\underset{Sucrose}{H22}O11 + H2O -> \underset{D - (+) - Glucose}{C6H12O5} + \underset{D - (-) - Fructose}{C6H12O5}}\]
