Q.Assertion (A): Hydrolysis of sucrose is known as inversion of cane sugar.
Reason (R): Sucrose is a disaccharide.

Sucrose: Hydrolysis and Inversion of Cane Sugar

Sucrose (cane sugar), $C_{12}H_{22}O_{11}$, is a disaccharide built from one $\alpha$-D-glucose and one $\beta$-D-fructose unit joined by a glycosidic linkage between C1 of glucose and C2 of fructose. Because this linkage ties up both anomeric (reducing) carbons, sucrose has no free aldehyde or keto group and is therefore a non-reducing sugar — it does not respond to Tollens' or Fehling's tests.

On hydrolysis, with dilute acid or the enzyme invertase, sucrose splits into equal amounts of its monosaccharides:

$C_{12}H_{22}O_{11} + H_2O \xrightarrow{\ H^+/\text{invertase}\ } \underbrace{C_6H_{12}O_6}_{\text{glucose}} + \underbrace{C_6H_{12}O_6}_{\text{fructose}}$ …
