Compound D: ethanol, acetone, or diethyl ether.
The boiling points for the compounds are 118 °C and 35 °C respectively. The solubility for both compounds is the same (8g/100g water). Explain this observation for (i) boiling point disparity; (ii) solubility similarity H-bonds form in diethyl ether; n-butyl alcohol forms H-bonds in water H-bonds form in n-butyl alcohol; diethyl ether forms H-bonds in water H-bonds in n-butyl alcohol; Both compounds form H-bonds in water O Both compounds form H-bonds; Both compounds form H-bonds in water
You are given an impure sample of fluorene. Your crystallization solvent choices are water, methyl alcohol and toluene. Using your understanding of polarity and solubility, predict which solvent would be the best choice for crystallization. Briefly explain your answer choice and why the other two choices were eliminated.

Propose a method to separate a mixture containing phenol, benzoic acid, naphthalene, and p-nitroaniline. Phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in either sodium hydroxide or sodium bicarbonate solutions. Write out the structures of the molecules in your scheme.
Suppose you took your two compounds, dissolved them in tertbutyl methyl ether and then added them to a separatory funnel. Now suppose you add in aqueous sodium bicarbonate and vigorusly shake the contents of the separatory funnel. ethanol will be dissolved in tert butyl methyl ether ether and valeric acid will be dissolved in the aqueous sodium bicarbonate layer. Draw the EXACT chemical structure that will exist in each of the layers after shaking with sodium bicarbonate. (Is it neutral or charged?)
methyl alcohol and ethyl alcohol are poor extraction solvent. why?

For the reaction shown below, 582 mg of 4-chlorophenol, 798 mg of benzyl bromide, and excess sodium hydroxide are used to obtain 847 mg of 4-chlorophenyl benzyl ether. What is the percent yield of 4-chlorophenyl benzyl ether? 4-chlorophenol MW = 129 g/mol; benzyl bromide MW = 171 g/mol; sodium hydroxide MW = 40.0 g/mol; 4-chlorophenyl benzyl ether MW = 219 g/mol
Cis-3-hexene and trans-3-hexene can be separated using GC. Explain why these two compounds can be separated by GC and not by fractional distillation.
Under certain conditions, mixing furan with maleic anhydride in diethyl ether yields a crystalline solid with a melting point of 114°C. When melting of this compound takes place; however, one can notice that the melt evolves a gas. If the melt is allowed to solidify, one finds that it no longer melts at 114°C but instead melts at 56°C. Provide an explanation for what is taking place.
