Diethyl ether is a good solvent to be used with Grignard reagents. Which of the following explanations for this laat alle! It can serve as a Lewis base and stabilize the Grignard reagent. It has a very high boiling so it can be heated to drive the Grignard formation to completion. It is polar enough to stabilize the Grignard reagent. It is aprotic and thus is not acidic enough to react with the Grignard reagent.
1. will a Grignard reagent be formed if acetone is used as solvent instead of diethyl ether. (reaction of bromobenzene with magnesium) 2. what is the product if reacting benzaldehyde with the Grignard reagent from Q1 in acetone?
if in project 7.1, 100% ethanol was used as the reaction solvent instead of diethyl ether, what would the product(s) of the reaction be? be sure to explain the formation of your predicted products. 2. If in Project 7.1, 100% ethanol was used as the reaction solvent instead of diethyl ether, what would the product(s) of the reaction be? Be sure to explain the formation of your predicted products. MgBr HOCH CH3
Could acetone be used instead of diethyl ether to dissolve an unknown mixture and perform the microscale separation via liquid/liquid extraction of your basic,acidic, and neutral components? Explain your answer.
Briefly, explain why your 3.0 mL reaction vial and diethyl ether solvent need to be completely dry (free of water)? Support your argument with a reaction equation between your Grignard reagent and water. What does the water do to the phenyl magnesium bromide? Briefly, explain why 3 M HCI (aq.) = [H_3O^+/CI-] hydrochloric acid used instead of a base for the work-up procedure? What did you observe when a low pH was obtained? What was the purpose of NaHSO_3 (sodium...
Lab: Grignard Reaction - Triphenylmethanol Why was the petroleum ether used to remove the biphenyl from the product? Apparently, it does not dissolve triphenylmethanol. (Explain in 3-4 Sentences)
lo (6 points) a. Why must ether used as solvent for the Grignard be scrupulously free of water or alcohol? b. 1-butanol, diethyl ether and pentane have close molecular weight but different boiling point, 1-butanol having the highest boiling point. Explain these observations
i need help with the prelab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
Why does petroleum ether have boiling point range while diethyl ether has a boiling point?
14. (3 pts.) The ionized benzoic acid dissolves better in water than it does in diethyl ether, which is how and why it is extracted into the water phase. Give the most important IMFs that are responsible for solubilizing the benzoic acid anion in the water. Give also the most important IMFs that are responsible for solubilizing the sodium cation in the water. The kinds of strong IMF that could be present are ion-dipole, hydrogen bonding (ignore dipole-dipole and induced...
