Identify the longest continuous carbon chain in the given compound. Here, the structure is a straight chain of carbon atoms connected by single bonds.
Count the number of carbon atoms in this longest chain. Each 'CH3' or 'CH2' group represents a carbon atom, so count them sequentially.
Determine the corresponding alkane name based on the number of carbons in the chain. The general formula for alkanes is CnH2n+2, and the names are derived from the number of carbons: 3 carbons = propane, 4 = butane, 5 = pentane, 6 = hexane, etc.
Since the compound is a straight chain with no branches or functional groups, the IUPAC name is simply the alkane name corresponding to the number of carbons counted.
Match the counted number of carbons to the options provided to select the correct IUPAC name.
