The Lewis structures for four liquids (A, B, C, D) are shown below. Answer the questions that follow, referring to these structures. (20 pts) 1. A. B. C. H3C-O-H D. a. Fill in the lone pair electrons on the drawings for A, B, and C. b. Which solvent will be best at dissolving wax? c. Which compound(s) will dissolve in water? d. Which compound(s) have dipoles? e. Which compound(s) have London Dispersion Forces? f. For which compound do you think surface tension will be greatest? g. Which compounds) will be able to hydrogen bond with liquid ammonia (NH,)? h. Sketch a hydrogen bonding interaction from part e. If you had more than one answer for e, (wax is a mixture of solid hydrocarbons) Sketch a hydrogen choose only one molecule to show in your sketch Structure E (below) is an isomer (alternative structure) of compound D. Briefly compare physical properties of D and E in terms of viscosity, boiling point and vapor pressure and relate these to the structure of the molecules. i. E. H3C CH3 CH3
