검증된 단계별 안내1
Identify the molecular formula given in the problem, which is C4H10.
Determine the number of carbon atoms in the compound. The molecular formula C4H10 indicates there are 4 carbon atoms.
Recall the IUPAC naming convention for alkanes, which is based on the number of carbon atoms: 1 carbon is 'meth-', 2 carbons is 'eth-', 3 carbons is 'prop-', 4 carbons is 'but-', and so on.
Since the compound has 4 carbon atoms, the prefix 'but-' is used, and since it is an alkane (saturated hydrocarbon), the suffix '-ane' is added.
Combine the prefix and suffix to form the IUPAC name: 'butane'.
