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, where the prefix indicates the number of carbon atoms: 'meth-' for 1, 'eth-' for 2, 'prop-' for 3, 'but-' for 4, 'pent-' for 5, and so on.
Match the number of carbon atoms (4) to the appropriate IUPAC prefix, which is 'but-'.
Combine the prefix with the suffix '-ane' (used for alkanes) to form the name 'butane', which is the correct IUPAC name for the compound C4H10.
