Question

Hydrolysis of starch yields

• A. sucrose
• B. fructose
• C. glucose
• D. gluconic acid

Answer 1

The correct option is C glucose

Glucose is the monomer of many of the larger carbohydrates, namely starch, cellulose. Hydrolysis of starch give glucose.
Glucose is obtained by hydrolysis of starch by heating it with dilute $H_{2}S{O}_4$ at $393K$ under pressure.

$(C_6{H}_{10}{O}_5{)}_n\underset{\text{Hydrolysis}}{\overset{H_3{O}^{+}}{\to }}n{C}_6{H}_{12}{O}_6\text{Starch}\alpha -D-\text{Glucose}$

Hence, the correct option is (c).
