검증된 단계별 안내1
Identify the longest continuous carbon chain in the given structure. The structure is CH\(\sub{3}\)-CH\(\sub{2}\)-CH\(\sub{2}\)-CH\(\sub{2}\)-CH\(\sub{3}\), which consists of 5 carbon atoms connected in a straight chain.
Recall the IUPAC nomenclature for alkanes, where the suffix '-ane' is used for saturated hydrocarbons (alkanes) and the prefix indicates the number of carbon atoms in the longest chain: 1 carbon = methane, 2 carbons = ethane, 3 carbons = propane, 4 carbons = butane, 5 carbons = pentane, 6 carbons = hexane, etc.
Since the longest chain has 5 carbon atoms, the base name of the compound will be 'pentane'.
Check for any substituents or branches attached to the main chain. In this structure, there are no branches or substituents; it is a straight-chain alkane.
Therefore, the correct IUPAC name for the compound is 'pentane'.
