- Answer each question and justify your answer by doing ALL of the following: • Identify the type of substance and important interparticle force(s) for both substances. − Explain how you know (substances and forces). − For each molecular substance, fully justify how you know if it is polar or nonpolar. Provide a Lewis structure, a geometry sketch, calculation of |ΔEN| values, and a discussion of symmetry. • Identify which of the two substances has stronger interparticle forces. If they have the same type of interparticle force, explain how you know which is stronger. • Answer the question by connecting the property asked about to strength of interparticle forces. • Use complete sentences, write all words out (no abbreviations) and be specific and complete with all explanations.
