Question

The reaction of dilute HCl with Maltose gives:

• A. D – glucose
• B. D – fructose
• C. D – glucose and D – fructose
• D. D – galactose

Answer 1

The correct option is A

D – glucose

Explanation for Correct answer:

Correct answer (A) D – glucose

• Maltose is formed from two molecules of glucose and these two molecules bond together by removing the water molecules.
• Maltose won't exist freely in nature and it is an intermediate product of starch hydrolysis.
• It is a Disaccharide with an alpha Glycosidic linkage between two D-Glucose molecules.
• The carbon atoms undergo mutarotation, so an equilibrium mixture of alpha and beta molecules forms.
• Maltose is a disaccharide and it contains D-Glucose which is a monosaccharide, so when diluted Hydrochloric acid reacts with Maltose, the hydrolysis process happens and gives D-Glucose.

• D-glucose is a short name given to dextrorotatory glucose and it is one of the stereoisomers of glucose.
