Which of the following compound is paramagnetic ? .

Options

A. `K_(2)O_(2)`
B. `O_(3)`
C. `KO_(2)`
D. `N_(2)O`

Explanation

To determine which of the given compounds is paramagnetic, we need to identify if any of them contain unpaired electrons. The compounds in question are K2O2 (potassium peroxide), ozone (O3), KO2 (potassium superoxide), and N2O (nitrous oxide).

### Step-by-Step Solution:

1. **Understanding Paramagnetism and Diamagnetism**:
- Paramagnetic substances have one or more unpaired electrons, which makes them attracted to magnetic fields.
- Diamagnetic substances have all electrons paired, resulting in a weak repulsion from magnetic fields.
