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....

hi, please help me with number 7. thank you
EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...

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...
