Question

you are analyzing a compound in a laboratory.you find that it is made up of carbon, hydrogen,and oxygen in a ratio of two hydrogen atoms for each carbon atom. how will you classify the compound? carbohydrate lipid protein nucleic acid

Explanation:

To classify the compound, we analyze the elemental ratio (2 H per C, along with O) and compare with biomolecule classes:

• Carbohydrates: Have the general formula \( C_n(H_2O)_m \), meaning a 2:1 H:O ratio (and H:C ratio often 2:1 in simple sugars like monosaccharides). This matches the given H:C ratio (2:1) and elemental composition (C, H, O).
• Lipids: Have a higher H:O ratio (much more H than O) and do not follow the 2:1 H:C pattern consistently.
• Proteins: Contain nitrogen (and often sulfur) in addition to C, H, O, so they are excluded.
• Nucleic Acids: Contain phosphorus and nitrogen (in addition to C, H, O), so they are excluded.

Answer:

A. carbohydrate
