Question
**Exercise 7:**

**Objective:** Label all the C=C double bonds as Z/E in the following compounds. If there is no Z/E isomer, mark as "no isomer."

**Structures:**

1. **Compound 1:** 
   - A cyclohexene derivative:
     - There are three substituents: two methyl groups (Me) and one hydrogen (H).
     - The methyl groups are on opposite sides of the ring, suggesting this may be examined for E/Z configuration.

2. **Compound 2:** 
   - An alkene with methyl (Me) and chlorine (Cl) substituents:
     - Contains two terminal hydrogens (H).
     - The configuration around the double bond needs to be assessed for isomerism.

3. **Compound 3:** 
   - An alkene with three hydrogen (H) atoms and one chlorine (Cl):
     - The linear arrangement features a C=C double bond, possibly allowing for E/Z evaluation.

4. **Compound 4:**
   - A cyclodecene structure:
     - Cycloalkene with no substituents protruding, likely indicating no E/Z isomerism due to symmetrical nature.

5. **Compound 5:**
   - A cyclopentenediol derivative featuring bromo (Br) and boronic acid (BO₂H₂) groups:
     - This compound has substituents on a cyclic double bond with potential E/Z isomerism.

6. **Compound 6:**
   - Includes a C=C bond with fluorine (F), chlorine (Cl), and bromine (Br):
     - The substituents around the double bond allow evaluation for Z/E isomerism. 

**Instructions for Educational Use:**

- Analyze each structure for possible geometric isomerism around the C=C bond.
- Apply the Cahn-Ingold-Prelog priority rules to determine if the highest priority substituents are on the same side (Z) or opposite sides (E) of the double bond.
- Note cases where there are no stereochemically distinct substituents resulting in "no isomer."
