Question

Sucrose on hydrolysis gives

Accepted Answer

Correct Answer: B — α-D-Glucose + β-D-FructoseStep-by-step Solution:Sucrose is a disaccharide formed by the condensation of α-D-glucose and β-D-fructose. The glycosidic bond is formed between C-1 of α-D-glucose and C-2 of β-D-fructose (1→2 glycosidic linkage). On hydrolysis with dilute acid or the enzyme invertase (sucrase), this bond is cleaved to regenerate α-D-glucose and β-D-fructose.Why other options are incorrect:Option A (α-D-Glucose + β-D-Glucose) is the hydrolysis product of maltose, not sucrose. Option C gives two units of fructose, which is not possible from sucrose. Option D reverses the anomeric configurations; sucrose yields α-D-glucose and β-D-fructose, not β-D-glucose and α-D-fructose.Key Concept: Sucrose (C₁₂H₂₂O₁₁) is a non-reducing sugar because both anomeric carbons are involved in the glycosidic bond. Its hydrolysis causes inversion of optical rotation from dextrorotatory (+66.5°) to levorotatory, hence the hydrolysis mixture is called invert sugar.
