Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H2O B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can’t break D. They have weak ionic bonds that cause them to precipitate E. The higher pressure of water causes solids to precipitate

a) An Organic compound is largely non-polar and thus quite soluble in pentane (b.p. 36 degrees C). Why would pentane be a poor choice for thermal cycling recrystallization? Suggest a different solvent in which the recrystallization would proceed better? b) What effect on the melting point would be observed if a very high BP solvent (like methylnaphthalene) was used in a recrystallization and traces of it were left unevaporated in the purified material?
