Question

The acidic hydrolysis of sucrose is called inversion reaction.
If true enter$1$, else enter $0$.

Answer 1

When acidic hydrolysis of sucrose is carried out, we get glucose and fructose as products. Actually, the reactant i.e. sucrose is dextrorotatory but upon acidic hydrolysis it turns into laevorotatory

Complete answer
Yes, the acidic hydrolysis of sucrose is called inversion reaction. Also the product sugar is known as invert sugar. The hydrolysis of sugar is carried out in an acidic medium. Due to this reason the reaction is said to be acidic hydrolysis of sucrose.
This can be understood with the help of the concept of specific rotation of various sugars involved in this reaction. The specific rotation of sucrose is $+ {66.5^{\circ}}$. But the specific rotation of glucose is $+ {52^{\circ}}$ and that of fructose is $- {92^{\circ}}$. When we derive the total specific rotation of products i.e. glucose and fructose it is.
Since here the sign of specific rotation changes, this means there is an inversion of sign of specific rotation. This inversion of rotation is referred to as inversion of sugar and the sugar thus formed is referred to as inverted sugar.
The reaction of acidic hydrolysis of sucrose can be explained with the help of following chemical equation;
Therefore, sucrose upon acidic hydrolysis i.e. reacting with water in presence of hydrochloric acid forms glucose and fructose. The sign of total optical rotation of products changes which means there is inversion of sign. The optical orientation changes from dextrorotatory to laevorotatory. So the reaction is also known as inversion reaction.

**Hence, $1$ will be the correct option.

Note:**
Thus, the acidic hydrolysis of sucrose is carried out in the acidic medium such as hydrochloric acid. The products formed are glucose and fructose. During the whole process of hydrolysis, the dextrorotatory sucrose leads to the formation of laevorotatory products. There is an inversion of optical orientation in the reaction. That is why the reaction of acidic hydrolysis of sucrose is known as inversion reaction and the sugars obtained as products are said to be inverted sugar.
