-Why was it so important to keep your glassware dry when synthesizing your Grignard? What happens...
Why is it important to oven dry or flame dry glassware before setting up a Grignard reagent formation or a Grignard reaction? Organomagnesium reagents react readily with water faster than with the desired starting material, lowering the overall yield Water will make the reaction blow up Wet glassware is slippery Too many salts will form in the reaction
7. (1 pt) Why was it important to exclude water from your apparatus, glassware and reagents that are being exposed to the Grignard reagent? Write a chemical equation that supports your explanation
Why is it important for all of your glassware to be clean and dry before performing a titration? Why are air bubbles in the burette tip a possible source of error in a titration experiment? How do you remove air bubbles from the burette tip?
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....
In Grignard reaction, the ether solvent must be very dry. What organic product is formed when phenyl magnesium bromide reacts with water? OH a b d OOOO
If you used a reaction tube that is not completely dry in this Grignard Reaction experiment, what organic byproduct would you expect? How much water (in µL) would it take to react completely with the desired product? Show your calculation. (Presume that one H2O is needed for each RMgX.)
Why is it so important to keep the silica gel saturated with solvent at all times during preparation and development of a column? How would the quality of separation be affected if the column was allowed to run dry? 3.
You cleaned your glassware prior to beginning but didn't ensure that it was completely dry and contaminated your reaction with Acetone. What effect would this have on the reaction? Draw any possible byproducts that may result from this contamination.
In a reflux apparatus, why is it important for joints between glassware to be keck clipped and properly greased? A. To ensure that water does not leak from the condenser. B. It does not matter, as we are not collecting the vapor. C. None of these answer choices are correct. D. To ensure a tight seal to prevent the loss of solvent over the course of the reaction.
What are anaplerotic reactions and why are they important? If a bacterial cell was actively synthesizing amino acids, would you expect more or less PEP carboxylase activity? Why
