Explaining Vapor Pressure in Terms of IMFs Given the shown structural formulas for these four compounds, explain their relative vapor pressures in terms of types and extents of IMFs: OH I H₂C-CH₂ ethanol HO OH | | H₂C-CH₂ ethylene glycol Solution CH₂CH₂OH: H-bonding & LDF. CH₂OHCH₂OH: Stronger H-bonding than ethanol (also LDF), and higher MM than H₂O. More viscous than ethanol, thus quite a low P vap.

Caffeine's solubility limit is about 2.2 %w/w in water at 25 Celsius degrees. Now, if I prepare a 5 %w/w PVA aqueous solution. Is the solubility limit increased or decreased (at room temperature) for this PVA solution? Why? Give me a very detailed explanation please.
Suppose you wanted to prepare a eutectic mixture of naphthalene and diphenylamine.Determine the masses of each naphthalene and diphenylamine required to make 6.000 gof a mixture at the eutectic composition.
The mixture contains benzoic acid, 2-napthol, and naphthalene. Dissolve the mixture in the polar solvent ether. When you react the mixture with 10% NaHCO3(sodium bicarbonatea weak base in aqueous solution) reacts with benzoic acid and forms sodium benzoate an ionic compound (similar to NaCl) that dissolves in aqueous solution (heavier than ether in density) and goes to the bottom of the centrifuge tube or to the bottom of the separatory funnel forming two layers. Then remove the bottom aqueous layer and collect in a beaker labeled as bicarbonate extract. Acidify the bicarbonate extract in the beaker to give benzoic acid. The top ethereal layer contains in the centrifuge tube or separatory funnel 2-napthol and naphthalene. To this top layer add 10% NaOH (sodium hydroxideis a strong base in aqueous solution reacts with only 2-napthol, a weak acid forming 2-napthoxide an ionic compound soluble in aqueous solution (similar to NaCl) that goes to the bottom of the centrifuge tube or to…
