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...

rewrite text in past tense Procedure-Simple Distillation 1. Take 60 ml of a 50:50 mixture of cyclohexane and toluene and place in a round bottom flask. Make sure you add a few boiling chips. 2. Assemble the distillation apparatus (See Figure 2.) and start the water flowing through the condenser. Place a graduated cylinder under the bent adapter so that you can measure the volume of distillate you collect. 3. Begin heating the sample with a heating mantle until it...

technique.
Section/Instructor SN2 Pre-lab (20 points) Answer on a separate piece of paper 1. (6 pts.) What is the purpose of the following experimental techniques and where in the procedure is each used? a. Heating under reflux b. Simple distillation c. Water wash d. Addition of COLD NAOH e. Saturated NaCl solution f.

The alcohol could easily be converted to a tosylate, a good
leaving group, and a conventional substitution reaction could have
been performed instead of the nucleophilic aromatic substitution
(NAS) reaction. Why was the NAS reaction the preferred method?
(Hint : Look up the nucleophiles of both reactions on chemical
manufacturing site.)
Part A: Synthesis of (t)-N,N-dimethyl-3-phenyl-3-(4- trifluoromethylphenoxy)propanamine 1. To the 250-mL round-bottom flask (RBF) containing (t)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-...

Please help with calculating the yield on this first page...the
other two are data for your calculations. I believe the limiting
