Q. Which of the following statement(s) is/are false about carbohydrates?
I. It has general formula, $C _{x}\left( H _{2} O \right)_{y}$.
II. They are hydrates of carbon.
III. The molecular formula of glucose is $C _{6} H _{12} O _{6}$ and general formula is $C _{6}\left( H _{2} O \right)_{6}$.
Choose the correct option.

Biomolecules

Solution:

The general formula of carbohydrates is $C _{x}\left( H _{2} O \right)_{y}$ and these were considered as the hydrates of carbon. Molecular formula of glucose $\left( C _{6} H _{12} O _{6}\right)$ fits into this general formula $C _{6}\left( H _{2} O \right)_{6}$.
