Carbon Suboxide has the formula

Options

A. `H_2CO_3`
B. `C_2 O_3`
C. `C_3 O_2`
D. `CO`

Answer

To determine the molecular formula of carbon suboxide, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: We need to find the molecular formula for carbon suboxide. The name "carbon suboxide" suggests it contains carbon and oxygen.

2. **Understanding the Name**: The prefix "sub" usually indicates that there is a lower oxidation state of the element involved. In this case, it implies a specific arrangement of carbon and oxygen atoms.

3. **Consider Common Formulas**: We need to recall common molecular formulas associated with carbon and oxygen. Carbon typically forms compounds like CO (carbon monoxide), CO2 (carbon dioxide), and in this case, we are looking for a compound that has multiple carbon atoms and fewer oxygen atoms.

4. **Analyze the Options Provided**: The options given are:
- Option 1: H2CO3 (carbonic acid)
- Option 2: C2O3
- Option 3: C3O2
- Option 4: CO

We can eliminate options that do not match our expectations for carbon suboxide.

5. **Determine the Correct Formula**: Among the options, C3O2 stands out. This indicates three carbon atoms and two oxygen atoms.

6. **Confirm the Structure**: The structure of carbon suboxide (C3O2) can be represented as O=C=C=C=O, which shows a series of double bonds between the carbon atoms and the oxygen atoms. This confirms the presence of cumulative double bonds.

7. **Conclusion**: Therefore, the molecular formula for carbon suboxide is C3O2.

### Final Answer:
The molecular formula of carbon suboxide is **C3O2**.
