Arrange the following molecules in order ionic character of their bonds
` LiF , K_(2)O , N_(2),SO_(2), ClF_(3)`

Explanation

To arrange the given molecules in order of ionic character of their bonds, we need to analyze the differences in electronegativity between the atoms in each molecule. The greater the difference in electronegativity, the more ionic character the bond will have.

### Step-by-Step Solution:

1. **Identify the Molecules:**
The molecules we need to analyze are:
- LiF
- K2O
