What is the general formula of monosaccharides?
Correct answer: B. (CH2 O)n
- A. Cx (H2O)Y
- B. (CH2 O)n
- C. Cn (H₂O)n
- D. Cn (H2 O)n−1
Explanation
The correct answer is(CH₂O)n, which is the general formula for monosaccharides. Monosaccharides are simple sugars that follow the empirical formula (CH₂O)ₙ, where 'n' can be 3, 4, 5, 6, etc., indicating the number of carbon atoms. This formula reflects the 1:2:1 ratio of carbon, hydrogen, and oxygen, respectively. Option A (Cx (H₂O)Y) and Option C (Cn (H₂O)n) are more generic and do not specify the typical monosaccharide ratio. Option D (Cn (H2O)n−1 ) incorrectly implies that there are fewer water molecules than carbon atoms, which does not match the monosaccharide structure.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
