The dipole moment of HBr is `2.6 xx 10^(-30)` C m, and the interatomic spacing is 1.41 Å. What is the per cent ionic character of HBr?

Explanation

To find the percent ionic character of HBr, we can follow these steps:

### Step 1: Understand the dipole moment
The dipole moment (μ) of HBr is given as \(2.6 \times 10^{-30} \, \text{C m}\). This value represents the actual dipole moment of the molecule.

### Step 2: Calculate the maximum dipole moment
The maximum dipole moment (μ_max) for a completely ionic bond can be calculated using the formula:
\[
