The electronegativities of the elements are H=2.1, O=3.5, F=4.0, S=2.5, Cl=3.0. Determine (calculate) the electronegativity diffrences for the following molecules and explain how they are arranged in the order: H2, O2, HCl, HF, H2O and position them in the following designations.
Covalent bond-Polar Covalent Bond-Polar Bond. I have tried this question countless times and need help on how to calculate and determine the answers.
