Question

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

Answer 1

Hydrolysis of sucrose is often spoken of as inversion and the resulting sugar as invert sugar. The reason for this name is found in the effect of invert sugar upon a beam of light. If a straight beam of light is allowed to pass through a solution of sucrose in an instrument called a polariscope, the beam of light is rotated to the right and the sucrose is called dextro-rotary. After the sucrose is hydrolyzed, the ray of light is rotated to the left and the invert sugar is levo-rotary. Because of this inversion of a beam of light, hydrolyzed sucrose is called invert sugar. Dextrose is dextro-rotary and sucrose is levo-rotary. It is due to the fact that levulose rotates the beam of light further to the left than dextrose rotates it to the right that the rotation of invert sugar is opposite to that of sucrose.
