Question

A molecule with the formula C₁₈H₃₆O₂ is probably a
A)carbohydrate.
B)fatty acid.
C)protein.
D)nucleic acid.
E)hydrocarbon.

Accepted Answer

The formula C₁₈H₃₆O₂ suggests a long-chain hydrocarbon with a carboxylic acid functional group at one end (the "acid" in fatty acid). This is characteristic of the structure of fatty acids, which are important building blocks of lipids. Carbohydrates, proteins, and nucleic acids have different chemical formulas and functional groups.
