Answer each question and justify your answer by doing ALL of the following: Identify the type of substance and important interpartide 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 AEN| 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. Do not refer to any actual data.
