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
Having trouble analyzing this HNMR spectra for my ochem 2 lab. We did a Grignard reaction with fructone, 2 equivalents of phenylmagnesium bromide, ether, and NH4Cl to create a tertiary alcohol (our product). Posting this H NMR spectra along with the reaction we did in this step of the synthesis. My main question is where on the spectra is my tertiary alcohol and how much of it do I have along with any other significant findings in this spectra. Thank...

A Grignard reaction was performed using the following steps: Step 1: Addition of Grignard Reagent: Phenyl Magnesium Bromide a solution of phenyl magnesium bromide (2.7 mL of a 3.0 M solution in anhydrous diethyl ether) and 5 mL of anhydrous diethyl ether was dispensed into the round-bottom flask and stirred with a stir bar. Step 2: Addition Formation: Reaction with Benzophenone A solution of 0.72 g (mp = 48-49 degrees C) of benzophenone and 2.0 mL of anhydrous diethyl ether...
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...
