Verified step by step guidance
1
Identify the longest continuous carbon chain in the given structure. The structure is CH\_3-CH\_2-CH\_2-CH\_2-CH\_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 = ethane, 3 = propane, 4 = butane, 5 = pentane, 6 = hexane.
Since the longest chain has 5 carbon atoms, the base name of the compound is 'pentane'.
Check for any branches or substituents on the main chain. In this case, the structure is a straight chain with no branches, so no additional prefixes or numbers are needed.
Conclude that the correct IUPAC name for the compound CH\_3-CH\_2-CH\_2-CH\_2-CH\_3 is 'pentane'.
