Effect of Differences in Electronegativity on Molecular Polarity For each molecule:  Sketch each molecule as shown in the simulation. Include arrows to show the bond dipoles as well as a molecular dipole (if present). Circle polar or nonpolar to indicate the polarity of the molecule. Fill in the electronegativity values for each atom   O2 vs HF O2 HF               polar nonpolar polar nonpolar Electronegativity O = H= F = Question 2a:  Both of these molecules have the same molecular geometry; they are linear.  How do differences in electronegativity affect the molecular polarity in linear molecules?

Decide whether each molecule or polyatomic ion is polar or nonpolar. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. For example, if the molecule were HCl and you decided the hydrogen atom was closest to the negative side of the molecule, you'd enter "H" in the last column of the table. polar or nonpolar? molecule or atom closest to polyatomic ion negative side polar Br2 nonpolar polar NH3 nonpolar polar H, S nonpolar
