Which of the following does not depict properties of fullerenes?

Options

A. Fullerenes are made by heating graphite
B. Fullerenes are pure forms of carbon.
C. Fulluerenes have open cage structure like ice.
D. `C_(60)` is called Buckminsterfullerene.

Explanation

To solve the question "Which of the following does not depict properties of fullerenes?", we need to analyze the properties of fullerenes and identify the incorrect statement among the given options. Here’s a step-by-step solution:

### Step 1: Understand what fullerenes are
Fullerenes are a form of carbon, specifically an allotrope, which means they have a unique structure and properties compared to other forms of carbon like graphite and diamond. The most common fullerene is C60, which has a spherical shape resembling a football.

**Hint:** Remember that fullerenes are a specific allotrope of carbon with distinct structural characteristics.

### Step 2: Identify the properties of fullerenes
1. **Allotrope of Carbon:** Fullerenes are indeed allotropes of carbon.
2. **Structure:** Fullerenes have a closed cage-like structure, not an open one.
3. **Preparation:** They can be synthesized by evaporating graphite using a laser.
4. **Hybridization:** The carbon atoms in fullerenes are typically sp2 hybridized.
5. **Solubility:** Fullerenes dissolve in organic solvents.

**Hint:** Focus on the structural characteristics and synthesis methods of fullerenes.

### Step 3: Analyze the options
Now, we will evaluate the given options based on the properties of fullerenes:

- **Option 1:** "Fullerenes are made by heating graphite."
- This statement is correct; fullerenes can be produced from graphite.

- **Option 2:** "Fullerenes are pure forms of carbon."
- This statement is also correct; fullerenes are considered one of the purest forms of carbon.

- **Option 3:** "Fullerenes have an open cage structure like eyes."
- This statement is incorrect. Fullerenes have a closed cage structure, not an open one.

- **Option 4:** "C60 is called Buckminster fullerene."
- This statement is correct; C60 is indeed known as Buckminster fullerene.

**Hint:** Compare each option against the established properties of fullerenes to find the incorrect one.

### Step 4: Conclusion
Based on the analysis, the option that does not depict the properties of fullerenes is **Option 3**, which incorrectly states that fullerenes have an open cage structure.

**Final Answer:** Option 3 is the correct answer as it does not depict the properties of fullerenes.
