Question

What is the percent of ionic character for the H-O bond in H2O?
Does this percentage mean that the H-O bond is ionic or covalent?

Answer 1

Use this formula: \(\large \sf \color{blue}{[1-e^{(\frac{[X_a-X_b]^2}{4})}] \times 100}\) where \(\sf \color{red}{X_a}\) and \(\sf \color{red}{X_b}\) is the electronegativity value of the two atoms in question: O and H, respectively.

Answer 2

I forgot to mention, that's using the electronegativity values on the \( pauling\) scale. I know sometimes people use mulken electronegativities for \(X\). Just wanted to clarify that.
