Final answer:
The alkane with the formula CH₃CH₂CH₂CH₂CH₂CH₃ is named hexane according to IUPAC nomenclature.
Step-by-step explanation:
The proper IUPAC name for the alkane with the condensed structural formula CH₃CH₂CH₂CH₂CH₂CH₃ is hexane. This molecule consists of a chain of six carbon atoms with single bonds between them and hydrogen atoms filling the remaining bonds to satisfy the tetravalency of carbon. According to IUPAC nomenclature rules for alkanes, each carbon atom is bonded to enough hydrogen atoms to give a total of four bonds for each carbon atom.
