If you conducted this experiment using (R) 2-bromobutane, what would be the stereochemistry of the product? How, if at all, would the stereochemistry of the product differ if the sodium iodide had not been included in the reaction mixture? This is the experiment: Formation of n-Butyl Acetate Just Below Reflux Set up a sand bath on a magnetic stirrer— start on “4” until it reaches 100°C To a 5-mL long-necked round-bottomed flask, add 0.750 g of sodium acetate trihydrate (NaOAc...

Refer to the assigned procedure and verify that an excess of NaBH4 is to be used for these reactions. Explain using calculations. We were unable to transcribe this imageAdd 2 mL of water. Heat the solution briefly to boiling. The solution should be clear and colorless. Transfer the clear, warm solution to a centrifuge tube using a filter pipet and allow to cool to room temperature. Add 4 mL of methylene chloride. Swirl and shake to mix the layers. Transfer...
Introduction A common method for synthesizing alkenes is by dehydrating (removing the elements of water) an alcohol. The dehydration is accomplished by heating the alcohol with either phosphoric or sulfuric acid. In this experiment, the dehydration reaction is illustrated by the conversion of 2-methylcyclohexanol to a mixture of alkenes (remember the Saytzeff rule). Information Each step of this E1 elimination reaction is reversible and thus, the reaction may be driven to completion by removing one or more of the products,...
5.0 ml of 2-methylcyclohexanol was placed in a 50 ml round bottom flask. Phosphoric acid (85%, 5 ml) was added cautiously, and the mixture swirled. Boiling stones were added to prevent bumping during heating. The mixture was heated to reflux temperature and refluxed for 15 minutes. The products were collected between 85-90 ˚C, in a small round bottom flask, cooled in ice water. Isolation Procedure The distillate was washed with 2 x 5 ml saturated sodium chloride solution in a...
Rewrite the text in past tense Use only third person, passive voice, e.g.: “Thirty grams of naphthalene was added 50 mL of m-xylene in a 250 mL round bottomed flask.” Experimental Procedure 1. Set up a simple distillation apparatus. 2. Add 16 g (16.7 mL) of cyclohexanol and 4 mL of concentrated sulfuric acid to the round bottom flask. Caution: Sulfuric acid is highly corrosive. Use caution and appropriate personal protective equipment! 3. Mix contents thoroughly and connect to distillation...
Assemble the glassware for fractional distillation according to the diagram and discussion above. Make certain that all joints are secure and that the apparatus is appropriately supported. Remember to allow for space below the distillation flask for the heating mantle and below the receiving flask for an ice bath. Pay extra attention to the positioning of the bulb of the thermometer as mentioned in the introduction. It is critical that the thermometer be positioned correctly for accurate temperature measurement. Using...
