Which of the following is a suboxide

Options

A. `Ba_2O`
B. `Pb_(2)O`
C. `C_(3)O_(2)`
D. ZnO

Explanation

To determine which of the given compounds is a suboxide, we need to understand what a suboxide is. A suboxide is a type of oxide that contains less oxygen than what is typically expected for that element.

Let's analyze the given options one by one:

1. **BA2O (Barium Oxide)**: This compound contains a typical ratio of barium to oxygen. Barium generally forms a stable oxide with a 1:1 ratio, so this is not a suboxide.

2. **PB2O (Lead Oxide)**: Lead oxides can exist in various forms, but PB2O suggests a higher ratio of lead to oxygen than expected. However, it does not fit the definition of a suboxide as it does not have less oxygen than expected.

3. **C3O2 (Carbon Suboxide)**: This compound is known as carbon suboxide. It contains less oxygen than the typical carbon oxides (like CO2), making it a suboxide.

4. **ZnO (Zinc Oxide)**: Zinc oxide has a typical 1:1 ratio of zinc to oxygen and does not qualify as a suboxide.

From this analysis, we can conclude that the correct answer is **C3O2**, which is a suboxide.

### Final Answer:
The suboxide among the given options is **C3O2 (Carbon Suboxide)**.
