The incorrect statement among the following is

Options

A. `C_(60)` is an allotropic form of carbon
B. `O_(3)` is an allotropic form of oxygen
C. `S_(8)` is only allotropic form of sulphur
D. Red phosphorus is more stable in air than white phosphorus

Answer

To determine the incorrect statement among the given options, we will analyze each statement one by one.

### Step 1: Analyze the First Statement
**Statement:** C60 is an allotropic form of carbon.
**Analysis:** This statement is correct. C60, also known as Buckminsterfullerene, is indeed an allotrope of carbon.

### Step 2: Analyze the Second Statement
**Statement:** O3 is an allotropic form of oxygen and O2 is an allotropic form of O3.
**Analysis:** The first part of this statement is correct; O3 (ozone) is an allotrope of oxygen. However, the second part is incorrect because O2 is not an allotropic form of O3. O2 and O3 are different allotropes of oxygen, but one is not an allotrope of the other. Therefore, this statement is partially incorrect.

### Step 3: Analyze the Third Statement
**Statement:** "Asset is only allotrope."
**Analysis:** This statement is incorrect because it implies that "Asset" (which seems to be a typographical error for "S8," the most stable form of sulfur) is the only allotrope of sulfur. Sulfur has several allotropes, including rhombic sulfur (S8), monoclinic sulfur, and plastic sulfur. Therefore, this statement is incorrect.

### Step 4: Analyze the Fourth Statement
**Statement:** Red phosphorus is more stable in air than white phosphorus.
**Analysis:** This statement is correct. Red phosphorus is indeed more stable in air compared to white phosphorus, which is highly reactive and can ignite spontaneously in air.

### Conclusion
After analyzing all statements, the incorrect statement is the third one, which claims that "Asset is only allotrope." This is incorrect because sulfur has multiple allotropes.

### Final Answer
The incorrect statement among the following is: "Asset is only allotrope."
