Question

What type of bond is present in atoms having electronegativity difference 1.5?

Answer 1

Hydrogen has an electronegativity of 2.0, while oxygen has an electronegativity of 3.5. The difference in electronegativities is 1.5, which means that water is a polar covalent molecule. This means that the electrons are drawn significantly towards the more electronegative element, but the atoms do not become ionized.
