An unknown solution was treated with H2SO4 and refluxed for 2 hours. The mixture was then washed with water and the organic layer was treated with 10% sodium bicarbonate until the aqueous solution drained off was basic. The organic layer was again washed with water, dried with magnesium sulfate, and filtered. The final product was propyl butyrate. What was the starting material and reactants?

What is the theoretical yield of tert-butyl chloride in this experiment? Synthesis of tert-butyl chloride: 25.5 mL of cold HCl and 15.7 mL of t-butyl alcohol in a separatory funnel then the aqueous layer is drained. Then washed with 15 mL of water and aqueous layer is drained again. Then washed with 15 mL of 5% sodium bicarbonate then drain aqueous layer. Lastly, 15 mL of water and drain aqueous layer.

Cyclohexanol is oxidized by a mixture of sodium hypochlorite and acetic acid. The solution is treated with sodium bisulfite and sodium hydroxide, before the product is extracted into dichloromethane. The organic layer was dried over potassium carbonate, decanted, and the product was obtained when the solvent was evaporated.

A chloride unknown sample weighing 0.4213 g is dissolved in acidic solution and is treated with the precipitating solution. The silver chloride precipitate that forms is filtered, washed, dried and weighed. The mass of the silver chloride obtained is 0.5915 g. Calculate the % Cl in this unknown sample. Molar Masses: AgCl = 143.35 g/mol, Cl– = 35.45 g/mol

A solution containing a mixture of metal cations was treated as outlined.Dilute HClwas added and a precipitate formed. The precipitate was filtered off.H2Swas bubbled through the acidic solution. Again, a precipitate formed and was filtered off.The pH was raised to about 9 and H2Swas again bubbled through the solution. No precipitate formed.Finally, sodium carbonate was added. A precipitate formed and was filtered off.What can be said about the presence of each of these groups of cations in the original solution?
