The product, when an alcoholic solution of sucrose is boiled with dilute hydrochloric acid or sulphuric acid is/are

50% glucose and 50% fructose

The correct answer is Option (3) → 50% glucose and 50% fructose

Sucrose is a disaccharide made up of two monosaccharide units: Glucose + Fructose These two units are linked by a glycosidic bond. When sucrose is heated with dilute acids like HCl or H₂SO₄, hydrolysis occurs.

Hydrolysis Reaction: Sucrose + H₂O → Glucose + Fructose 

The glycosidic bond breaks and one molecule each of glucose and fructose is formed.

Important Point: For every 1 molecule of sucrose hydrolyzed: 1 molecule of glucose is produced 1 molecule of fructose is produced

So the products are formed in equal molar proportion.

Why 50% each?

Since: 1 sucrose → 1 glucose + 1 fructose There is no preference or unequal formation.

Thus, the mixture contains: 50% glucose 50% fructose This mixture is called invert sugar.
