EXPT 13ab Report Perez

What factors during the experiment caused the percent yield to be different than 100%? What impurities may be present in the final product (look at the spectroscopic data for evidence of this), and how does that effect the percent yield calculation? I got 64% for the percent yield.

Qs5. Solubility of compound X in water is 3 g/100 mL; in ether 6 g/100 mL. & Suppose, you are to perform a regular extraction. (Mohring, pp142-147 & 161-162) 1) of the compound X can be extracted to the organic layer? How much will remain in the aqueous layer? If you add 6 g of the compound to in 50 mL of water and add 25 ml of ether, how much 2) the compound can be extracted? How much will you be able to extract totally (in these two extractions)? If you add a fresh 25-mL portion of ether to the same aqueous solution, how much of 3) same amount of X as in the previous double extraction? Why or why not? If you just do one extraction with 50-mL portion of ether, will you be able to extract the

Please identify compound 1 and compound 2!!! Attached is the H-NMR and IR for both compounds (ignore the IR peaks ~2400).  The experimental melting point for the aqueous layer was 260-261 celcius. The experimental melting point for the organic layer was 76.9-78.7 celcius.  The following was my procedure: IntroductionThe reaction mixture in this experiment contains 4-bromobenzaldehyde, methanol, and aqueous potassium hydroxide. A reaction occurs that produces two organic compounds, compound 1 and compound 2. Both are solids at room temperature. Your task is to isolate, purify, and identify both compounds. A specific procedure is given for preparing the compounds, but you will need to work out the procedures for most other parts of this experiment.Experimental ProcedureThis procedure should produce enough of each compound to complete the experiment; however, in some cases, it may be necessary to run the reaction a second time. Although this experiment can be done individually, it works…

Was this experiment green and were the solvents safe? Could other have alternatives been used (including less solvent)? Was this energy Intensive?

01:50 4G File Details 4CH003/UM1: Fundamentals of... Introduction NaBH4 OH C=0 H benzophenone diphenylmethanol Ketones are readily reduced to secondary alcohols by reaction with sodium borohydride. The aim of this experiment is to determine the time required to effect the complete conversion of the ketone, benzophenone to diphenylmethanol at room temperature. This investigation may be achieved by isolating and analyzing the reaction product after different reduction times. Infrared spectroscopy affords a convenient method of analysis; by comparing the IR spectrum of the crude reaction product at different time intervals one would expect to see the intensity of the hydroxyl absorption peak increase relative to that of the original carbonyl peak. From this you can deduce the optimum time for the reduction process at room temperature. Procedure Note the "reduction time" that the demonstrator assigns to your group. Different groups will be assigned different times, eithert = 2.5 minutes,…

During an acid base extraction of an organic compound dissolved in dichloromethane with sodium bicarbonate (NaHCO3), you do not recover any of the desired extracted product after completing all the remaining steps. What could the most probable reason(s) be for the observed outcome?   -The organic compound you want to extract is also a base; an acid is needed -You did not degassed/vent the separatory funnel -You did not shake the separatory funnel enough to react the base with the organic compound -You did not heat the mixture before the extraction -The organic compound evaporate from separatory funnel during the extraction

I don't know how to do this

I have this task in organic chemistry (book: Brown's introduction to organic chemisty, global edition). Task 10:42.  In (a) I have to tell what the funcion of K2CO3 is in step 1. Is it that CO32- take the hydrogen atom in 1-napthol? Will it then be a SN2 mechanism? In (b) I have to name the amine used in step 2 to form Propanolol. But I can't really find out how to come up with an amine that will make that reaction. Here are two pictures of the task:
