What is the BEST representation of the basic formula for any monosaccharide?

A) CH2O

B) C2H2O

C) (CH2O) n, where n is 1 or 2

D) (CH2O) n, where n can be 3-7

D) (CH2O) n, where n can be 3-7

Explanation:

Monosaccharides are the simplest carbohydrate that has a formula of (CH2O) n where n at least have to be 3. Since its the simplest form, monosaccharides can't be broken down into smaller carbohydrates.

If the number of n is less than 3, it won't become monosaccharides. A molecule with CH2O formula is called an aldehyde. That is why option C is wrong. The answer will be option D
