Carbohydrates are large molecules with the molecular formula Cx(H2O)y. In which of the following pairs is x not equal to y?

A.

glucose and starch

B.

maltose and starch

C.

sucrose and fructose

D.

galactose and starch

Correct answer is B

Glucose = C6(H2O)6

= C6H12O6

Maltose = C12 (H2O)11

= C12H22O11

Starch = C6 (H2O)5

= C6H10O5

Sucrose = C12 (H2O)11

= C12H22O11

Fructose = C6(H2O)6

= C6H12O6
