Question

Sucrose (cane sugar) is a disaccharide. One molecule of sucrose on hydrolysis gives ______.

Options

• 2 molecules of glucose

• 2 molecules of glucose + 1 molecule of fructose

• 1 molecule of glucose + 1 molecule of fructose

• 2 molecules of fructose

Answer 1

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.

\[\ce{C12\underset{Sucrose}{H22}O11 + H2O -> \underset{D - (+) - Glucose}{C6H12O5} + \underset{D - (-) - Fructose}{C6H12O5}}\]
