![### Assigning E or Z Configurations to Alkenes
**Question:**
Assign E or Z configurations to each alkene below.
**Chemical Structure:**
The image shows a chemical structure with the following details:
1. A cyclohexane ring (a six-membered ring comprised completely of carbon atoms).
2. Attached to one carbon on the cyclohexane ring, there is a methyl group (CH₃).
3. Another carbon on the cyclohexane ring is involved in a double bond (alkene) with a side chain.
4. The double bond has two substituents:
- One side of the double bond has a cyanide group (CN).
- The opposite side of the double bond has a propanol group (CH₂CH₂OH).
### Assigning E or Z Configuration
To assign the E or Z configuration to the given alkene, you need to follow these steps:
1. **Assign Priority:** According to the Cahn-Ingold-Prelog priority rules:
- The carbon contributing to the cyanide group (CN) will likely have a higher priority compared to the carbon linked to propanol (CH₂CH₂OH).
- On the cyclohexane ring side, you'd compare the priorities of the groups attached to the carbons involved in the double bond. Here, the substituent with the highest atomic number attached to these carbons will get higher priority.
2. **Determine Configuration:**
- If the two highest priority substituents on each carbon of the double bond are on the same side, the configuration is Z (from the German word "zusammen," meaning together).
- If they are on opposite sides, the configuration is E (from the German word "entgegen," meaning opposite).
Using the provided chemical structure, you can visualize and compare the priorities to assign the appropriate E or Z configuration.
### Conclusion
When analyzing this chemical structure, make sure you correctly follow the Cahn-Ingold-Prelog rules to assign the correct configurations. This is crucial for understanding the chemical behavior and interactions of the molecules involved.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff71695ef-d0f4-4003-9f93-ae5ca95ceb18%2Ffc98f741-524d-4c5a-a4d4-48a8b629a690%2Fhzanc9g_processed.jpeg&w=3840&q=75)
