Arrange the bonds in order of increasing ionic character in the molecules : `LiF, K_2O, N_2, SO_2 and ClF_3`.

Explanation

To arrange the bonds in order of increasing ionic character for the molecules LiF, K₂O, N₂, SO₂, and ClF₃, we will follow these steps:

### Step 1: Understand Ionic Character
Ionic character in a bond is influenced by the difference in electronegativity between the two atoms involved in the bond. The greater the difference in electronegativity, the more ionic character the bond will have.

### Step 2: Identify Electronegativity Values
We need to look up the electronegativity values of the elements involved in each bond:
- **Li (Lithium)**: 1.0
