Identify the molecular formula and structure of the compound given: it is a straight chain of six carbon atoms connected by single bonds, with the formula CH3-CH2-CH2-CH2-CH2-CH3.
Determine the longest continuous carbon chain in the molecule. Since there are six carbons in a row, the longest chain is six carbons long.
Recall the IUPAC nomenclature for alkanes: the name is based on the number of carbons in the longest chain, with the suffix '-ane' indicating all single bonds.
Match the number of carbons in the longest chain to the corresponding alkane name: 1 carbon is methane, 2 ethane, 3 propane, 4 butane, 5 pentane, 6 hexane, 7 heptane, and so on.
Since the longest chain has six carbons and there are no branches or substituents, the correct IUPAC name is 'hexane'.
