**Quiz Question: Identifying Stereogenic Centers**

**Question:**
How many stereogenic centers are present in the following compounds?

**Compounds:**

- **I**: Structure is a linear alkene with the molecular formula CH₃CH₂CH₂CH₂C=CHH.
- **II**: Structure is an ether with two ethyl groups connected by an oxygen atom.
- **III**: Structure is a cyclobutane ring with two chlorine atoms on adjacent carbons.

**Options:**

- ○ 1
- ○ 2
- ○ 3
- ○ 4

**Diagrams Explanation:**

1. **Compound I**:
   - A straight chain of five carbon atoms with a double bond between the fifth and sixth position.
   - This double bond does not introduce a stereogenic center since the carbon atoms are not bonded to four different groups.

2. **Compound II**:
   - An ether functional group linking two ethyl groups.
   - There are no stereogenic centers as there are no carbon atoms bonded to four different substituents.

3. **Compound III**:
   - A four-membered cyclobutane ring with two chlorine atoms.
   - The presence of substituents on the ring carbons potentially introduces stereogenicity depending on the spatial arrangement. 

**Note:** Stereogenic centers are typically carbon atoms bonded to four different groups, creating chirality.
