What is the IUPAC name for the alkane with three carbon atoms?

Explanation:
When naming alkanes, the name comes from a prefix that shows how many carbon atoms are in the main chain, plus the suffix -ane for a saturated hydrocarbon. For three carbons, the prefix is prop- and the suffix is -ane, giving propane. The structure is CH3-CH2-CH3, which is the only arrangement for C3H8, so the IUPAC name is propane. The other options correspond to different carbon counts: ethane has two carbons, butane has four, and pentane has five.
