검증된 단계별 안내1
Identify the number of carbon atoms in the longest continuous chain of the compound. The structure given is CH\_3-CH\_2-CH\_2-CH\_3, which contains 4 carbon atoms in a row.
Recall the IUPAC naming convention for alkanes, where the name is based on the number of carbons: 1 carbon is methane, 2 is ethane, 3 is propane, 4 is butane, and 5 is pentane.
Since the compound has 4 carbons in a straight chain, the base name corresponds to 'butane'.
Check for any substituents or branches on the main chain. In this case, there are none, so no prefixes or additional numbering are needed.
Conclude that the correct IUPAC name for the compound CH\_3-CH\_2-CH\_2-CH\_3 is 'butane'.
