Among the halogen hydrides, which has maximum per cent of ionic character ?

Explanation

To determine which halogen hydride has the maximum percent of ionic character, we can follow these steps:

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

### Step 2: Identify the Halogen Hydrides
The halogen hydrides we are considering are:
- HF (Hydrogen Fluoride)
