Grignard Reaction
Can someone give me a few ideas on the Grignard Reaction laboratory.
1. Write down which principles of chemistry involved in the experiment.
b. List the weaknesses and problems that may have affected the results in this laboratory.
c. Devide whether the grignard method is efficient or not, in terms of yield and purify
and as well, which layer was the organic layer when we added the Hcl acid? Thanks a lot, i really appreciate any support i can get on this.

This is for the Grignard Reaction laboratory. Please help me answer this question, much appreciated. 1. If a student performing Laboratory with Grignard reaction accidently used acetone as the reaction solvent instead of diethyl ether, what would the major organic product(s) be? Draw the structure of the product(s) (no mechanism necessary). b. What was the purpose of adding magnesium sulfate in this experiment? c. Grignard reagents react with both aldehyde and ketone functional groups. How do you predict the reaction...

These questions are about a lab on Grignard Reactions 10. (3) If you had done this reaction in the lab, you would have added the Grignard reagent to a carbonyl containing molecules such as the ones from question 3. After addition the reaction is usually opaque and forms white precipitate, what is the precipitate made of? In other words, what are the salts that form? 11. (3) After these salts have formed, the reaction is quenched with acid, 5 N...

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....

Product Isolation After stirring the reaction for 5 minutes and allowing the reaction mixture to cool (the reaction can be exothermic), remove the Claisen head from the conical vial. Slowly add 3 M HCl(aq) drop-wise. The solid may need to be broken up with a stirring rod or a pipet. Continue to add acid until the aqueous phase (bottom layer) tests positive with pH paper. Extractions can be done using the conical funnel...
