Question

1. you are analyzing a compound in the 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? a. lipid b. protein c. carbohydrate d. nucleic acid

Explanation:

Step1: Recall compound - element ratios

Carbohydrates typically have a ratio of hydrogen to carbon atoms of 2:1.

Step2: Analyze given ratio

The compound has two hydrogen atoms for each carbon atom, which matches carbohydrate ratio.

Step3: Eliminate other options

Lipids have a lower H:O ratio than carbohydrates. Proteins contain nitrogen in addition to C, H, O. Nucleic acids contain phosphorus and nitrogen in addition to C, H, O.

Answer:

C. carbohydrate
