Step 1: Break Down the Problem

To find the IUPAC name for cumene, we need to analyze its structure and determine its correct nomenclature.

Step 2: Relevant Concepts

1. Structure of Cumene: Cumene is an organic compound that consists of a propyl group attached to a benzene ring.
2. IUPAC Naming Conventions: In IUPAC naming, we identify the longest carbon chain connected to the functional group attached to the benzene ring.

Step 3: Analysis and Detail

1. Cumene Structure: The structure for cumene can be represented as:

   $C_6H_5 - C_3H_7$

   Where the phenyl (benzene) ring has a propyl group (C₃H₇) attached to it.

2. Identifying the Options:

   • Propylbenzene: This fits the description of cumene since it has a propyl group directly attached to the benzene ring.
   • Isopropylbenzene: This refers to a compound where an isopropyl group is attached to benzene, which is not cumene.
   • Isobutylbenzene: This is a different structure as it has an isobutyl group attached.
   • Toluene: This has a methyl (not ethyl or propyl) group attached to benzene.

Step 4: Verify and Summarize

Through analysis, the only option that accurately represents cumene, with the correct propyl group attached to benzene, is propylbenzene.

Final Answer

The IUPAC name for cumene is propylbenzene.
