3. For each of the following molecules/compounds: (a) Calculate the electronegativity difference (b) State whether the bonds in the molecule/compound are ionic, polar covalent, or non-polar covalent. (c) Draw the Lewis Structure of the molecule/compounds. (d) Redraw the molecule with the correct structural shape and, where applicable, draw dipole vectors. If the compound is ionic, simply identify the cation and anion. (e) Determine the molecular/compound polarity (i.e. is it polar or nonpolar)? [5A] Use the table to organize your information
