Question

How do you use an electron dot diagram to represent a molecule that has a polar covalent bond?

Answer 1

A polar covalent bond is still composed of 2 electrons, even if they are unequally shared..........

Explanation:

We could represent the hydrogen chloride molecule, which is certainly polar, as `""^(delta+)H-Cl^(delta-)`. Electron density is polarized towards the more electronegative atom. Is this what you wanted?
