To really evaluate the success of this synthesis, you will need to carefully consider the following; purity, percent yield, melting point behaviour. To say your experiment was a success and that you have made a reasonable amount of cholesteryl nonanoate, you want to make sure all of these were successful. Which of the following statements is true? 1- Cholesteryl nonanoate has been successfully prepared if the percent yield is 90%, the melting point was 74-86oC and liquid crystaline behaviour was...

Experiment 12: Synthesis of Benzoic Acid pre-lab (4 pts) 1 (2 pts) Refer to the introduction on the general process of hydrolysis of nitriles to carboxylic acids. Starting with benzonitrile (shown below), show how it is converted to benzoic acid under basic conditions. N 2) (2 pts) The reaction for the synthesis of benzoic acid via benzonitrile hydrolysis is shown below: 1) NaOH, HO YOH + NaCl 2) HCI, H,0 Benzonitrile Density = 1.0 g/mL MM = 103.04 g/mol Benzoic...

Name Lab Partner LAB 9 REFLECTIVE EXERCISES Lab Section 1 What data did you collect to indicate that you successfully produced aspirin? What did your results indicate about the purity of the aspirin you obtained? Explain your answers. 2 Given that the melting point of salicylic acid is 159 C, can you be certain that the product you isolated was not pure solicylic acid that was unchanged during the reaction? Can you be certain that the product you isolated was...

You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

1. Consider unknown compounds made of C, H and O atoms. Explain how you expect the water solubility of a compound to change as it's weight percent oxygen increases. 2. What is the advantage of using a mixed melting point analysis to identify a compound? Does your mixed melting point value identify your isolated material as cholesterol?

1. Why do soluble impurities affect the melting point while insoluble impurities are expected not to affect the melting point? (3 points) 2. Why cold solvents are preferred during recrystallization and when is recrystallization selected vs other purification techniques you have learned during 3210 labs. (3 points) 3. The solid compound "X" has two components (A and B). After heating the solid powder (X), one component (A) is left and the other component (B) evaporated directly. Comment on the nature...
