Vedclass · Answer

(A) Disaccharides are carbohydrates that yield two molecules of monosaccharides on hydrolysis. Their general formula is derived from the condensation of two monosaccharide units $(C_6H_{12}O_6)$ with the loss of one water molecule $(H_2O)$. Calculation: $2 	imes (C_6H_{12}O_6) - H_2O = C_{12}H_{24}O_{12} - H_2O = C_{12}H_{22}O_{11}$. Thus,the general formula for a disaccharide is $C_{12}H_{22}O_{11}$.
