검증된 단계별 안내1
Step 1: Understand the molecular formula C4H10. The formula indicates that the compound consists of 4 carbon atoms and 10 hydrogen atoms.
Step 2: Recall the IUPAC naming convention for alkanes, which is based on the number of carbon atoms in the longest continuous chain. The prefix 'meth-' is for 1 carbon, 'eth-' for 2 carbons, 'prop-' for 3 carbons, 'but-' for 4 carbons, and so on.
Step 3: Identify the number of carbon atoms in the given molecular formula. Since there are 4 carbon atoms, the prefix 'but-' is used according to IUPAC nomenclature.
Step 4: Combine the prefix with the suffix '-ane', which is used for saturated hydrocarbons (alkanes) with single bonds only. Therefore, the name becomes 'butane'.
Step 5: Verify the options provided: Pentane (C5H12), Hexane (C6H14), Butane (C4H10), and Propane (C3H8). The correct IUPAC name for C4H10 is 'Butane'.
