Which of the following statement is false about cabon ?

Options

A. `C_(60)` is also one of the allotrope of carbon
B. It has crystalline as well as amorphous allotropes
C. It can form `p pi-p pi` bonds with other c-atoms
D. It cAnnot form `p pi-p pi` bond with atoms such as `N` and `O `.

Answer

To determine which statement about carbon is false, we need to analyze the characteristics and properties of carbon, particularly focusing on its allotropes and bonding capabilities.

### Step-by-Step Solution:

1. **Understanding Allotropes of Carbon**:
- Carbon exists in several allotropes, which are different forms of the same element that have distinct physical properties but similar chemical properties.
- The two main categories of carbon allotropes are crystalline and amorphous.

2. **Identifying Crystalline Allotropes**:
- The crystalline allotropes of carbon include diamond, graphite, and fullerenes (e.g., C60).
- These allotropes have a well-defined structure and specific physical properties.

3. **Identifying Amorphous Allotropes**:
- Amorphous allotropes of carbon include substances like coal, coke, charcoal, and lamp black.
- These do not have a definite crystalline structure.

4. **Analyzing Carbon's Bonding Capabilities**:
- Carbon can form various types of bonds, including single, double, and triple bonds with itself and other elements.
- For example, in alkenes (like ethylene, CH2=CH2) and alkynes (like acetylene, HC≡CH), carbon forms double and triple bonds, respectively.

5. **Evaluating the Statement about P-Pi Bonds**:
- The statement in question suggests that carbon cannot form P-Pi-Pi bonds with nitrogen and oxygen.
- This statement is false because carbon can indeed form P-Pi-Pi bonds with other elements, including nitrogen and oxygen, as seen in functional groups like carbonyls (C=O) and cyanides (C≡N).

6. **Conclusion**:
- After analyzing the statements regarding carbon, the false statement is that carbon cannot form P-Pi-Pi bonds with nitrogen and oxygen. This is incorrect, as carbon can form such bonds.

### Final Answer:
The false statement about carbon is that it cannot form P-Pi-Pi bonds with atoms such as nitrogen and oxygen.
