How to calculate the melting point of Diebenzalacetone in the synthesis of Dibenzalacetone formation; please explain!
Recrystallization: Percent error of melting point and how impurities affect melting point: Please explain both questions below: (Part A) During a recrystallization experiment, the literature melting point of a compound is 105-107 °C. The melting point temperature you obtain from your recrystallized compound is 103-105 °C. Which of the following would be the proper way to set up the percent error of your mp? (a) (104/106)*100 (b) [(106-104)/106] *100 (c) (107/105)*100 (d) [(107-105)/107] *100 (Part B) For a recrystallization experiment...
Dibenzalacetone Synthesis PURPOSE: purpose of this lab exercise is to synthesize dibenzalacetone by means of an aldol condition. INTRODUCTION: Wow, is it wet in here or what? That's what happens when you condense, right? No, that is not right, you say! You can condense things without getting wet in organic chemistry. Think about aldol condensations, you tell me. Yes. yes..of course you are correct: organic condensations dont get you wet. They get you a new product. Silly me Aldol condensation...
please explain how this works 11. Which is most likely to have the lowest melting point? A. NaBr B. Cao C. LiF D. Mgo
The Aldol condensation: Synthesis of dibenzalacetone I need help with question 4 and the second part of 5 please.
Explain how rapid crystal growth effects the melting point of the compound. Will it raise or lower the melting point?
Hey can I please get some help to complete this worksheet that is based on Synthesis and Recrystallization of Dibenzalacetone lab. 4. If you were to measure the melting point prior to recrystallization, what would you expect (compared to the melting point of the recrystallized product)? As. Comment of the purity of the product 6. Describe the color of the product. What is responsible for this color? iǐne (for 낙 product is aAbrrǐut yellow. A 7. Functional group questions: What...
Explain mechanistically how DMF catalyzes the formation of the acid chloride (in the synthesis of N,N-Diethyl-m-toluamide)
A student carries out a synthesis of ibuprofen and obtains white solid with a melting of point 75-77° matching that reported in the literature of 75-77°C a. Explain why this information does not prove that the material synthesized was ibuprofen. b. Using only the technique of melting point determination, describe who the student could prove that the material they synthesized was ibuprofen.
1. How would you explain a percent recovery over 100% with an observed melting point higer than the literature melting point during an extraction lab? 2. How you you explain a low percent recovery during an extraction lab? 3. How does emulaion fomration affect the results of an extraction lab?
How does the melting point of an impure substance compare to the melting point of a pure substance?
