Grignard Reaction 1. Draw your complete reaction, including the formation of the Grignard reagent and the reaction with your carbonyl compound. Below each reagent, write its molecular weight and density (if a liquid). Also write how much of each material you will use in ml (if liquid), grams, and moles. Also include the molecular weight and melting point of your final product. 2. How many moles of Grignard reagent are you synthesizing? What mass of water could fully react with...

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....

5. Arrange the following solvents in increasing order of reaction rate for Diels-Alder reaction between anthracene and 1,3-dimethylcyclopentene. Draw structure of product with appropriate stereochemistry. 10 points Ethyl acetate diisopropyl ether Ethanol Water Hexane The same order of reactivity would not necessarily result in the highest yield of the product - meaning, the solvent with highest reactivity would not necessarily give you the most amount of product based on procedure employed in the lab. Explain why this is so.
