Question
**Question 8: IUPAC Nomenclature and Stereochemistry**

**Task:** 
Using IUPAC nomenclature and syntax, name the compound shown below. Include in the compound’s name the Z or E configuration.

**Graph/Diagram Explanation:**

The diagram shows a hydrocarbon chain with eight carbon atoms. The carbons are numbered from 1 to 8 along the longest chain:

- There is a double bond between carbon 4 and carbon 5.
- Methyl groups (CH₃) are attached to carbon 3 and carbon 4.

Notes handwritten next to the structure suggest determining whether the double bond has an E or Z configuration.

**How to Determine E/Z Configuration:**

The configuration (E or Z) of the double bond is based on the priority of the substituents attached to the carbons of the double bond, according to Cahn-Ingold-Prelog priority rules.

1. Look at the groups attached to each carbon of the double bond.
2. Assign priority based on atomic number: higher atomic number = higher priority.
3. Determine the relative positions of the higher priority groups:
    - If the higher priority groups are on the same side, the configuration is Z (from German *zusammen* meaning "together").
    - If the higher priority groups are on opposite sides, the configuration is E (from German *entgegen* meaning "opposite").

Please proceed to assign the correct name using these rules.
