Acetylation of ferrocene and column chromatography
Lab 4: Question 3 Homework • Unanswered Important ... The solvent is changed from petroleum ether to diethyl ether after the ferrocene is collected from the column. Why not use diethyl ether the entire time? Because diethyl ether is more polar than petroleum ether Because petroleum ether selectively elutes ferrocene since it contains more ether oxygens than diethyl ether Because diethyl ether would lead to a poorer separation of ferrocene and acetylferrocene Both a...

Please help with question 3. Thank you!
Disposal of waste: When necessary, all organic waste must be disposed into the organic waste container, all aqueous waste to the aqueous waste container and all solid waste to the solid waste container. Nothing is disposed in the sink or trash can. Synthesis of acetanilide In a dry small conical vial, dissolve 300 mg (or 30 drops) of freshly distilled aniline in 1.0 mL of 1.0 M hydrochloric acid. Swirl the mixture to...

Just Answer Question 5
Synthesis of 2-chloro-2-methylbutane (literature version) Concentrated aqueous hydrochloric acid (HCI, 3.3 equivalents) was slowly added to 2-methyl-2-butanol (1.0 equivalents) in a 100 mL round bottom flask with stirring. The reaction was stirred for 15 minutes at room temperature. Upon completion, the reaction mixture was transferred to a 60 mL separatory funnel and the aqueous layer was removed. The organic layer (i.e. the product) was successively washed with: (1) saturated aqueous NaCl (brine), (2) saturated aqueous NaHCO,...
