검증된 단계별 안내1
Identify the longest continuous carbon chain in the given compound. Count the number of carbon atoms in this chain.
Recall the IUPAC prefixes for alkanes based on the number of carbons: 'meth-' for 1, 'eth-' for 2, 'prop-' for 3, 'but-' for 4, 'pent-' for 5, 'hex-' for 6, and so on.
Since the compound is a straight chain with no branches or functional groups, the suffix will be '-ane' indicating an alkane (a saturated hydrocarbon).
Combine the prefix corresponding to the number of carbons with the suffix '-ane' to form the systematic name.
Verify that the name matches the structure: for a 5-carbon straight chain alkane, the correct IUPAC name is 'pentane'.
