Hint: Sucrose is the common table sugar we use in our daily lives. It is a disaccharide, i.e. it is composed of two sugars by a glycosidic linkage. The monosaccharides involved in the structure of sucrose are both six carbon compounds.
Complete answer:
Sucrose is a saccharose, also known by names such as table sugar, cane sugar, beet sugar, etc.
It is a carbohydrate, more specifically, a disaccharide, made up of two monosaccharides, namely, glucose and fructose.
Glucose is an aldehyde, which forms a six-carbon ring.
Whereas, fructose is a ketone, which forms a five-membered ring (hence, a furan).
Therefore, on hydrolysis sucrose will break into its monomeric sugars. The reaction can be represented as –
As we can see, sucrose is made by linking C1 of alpha-glucose and C2 of beta-fructose. The bond formed between glucose and fructose is known as 1,2-glycosidic bond.
Also, sucrose is a dextrorotatory sugar, which changes to levorotatory, due to the dominant levorotatory nature of fructose.
Therefore, the answer is – the products of hydrolysis of sucrose are glucose and fructose.
Additional Information: Fructose is the sweetest natural sugar.
Note: Disaccharides are reducing sugars, except sucrose. Sucrose is not a reducing sugar because the reducing groups of glucose and fructose are involved in glycosidic bonds. It, therefore, gives a negative Tollens test.
