4. Chose a Grignard reagent and a ketone that can be used to produce each of...
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....
4. Show how C2HsMgBr, the Grignard Reagent prepared from ethyl bromide, can be used as a starting material in the preparation of each of the following compounds он (a) Ph-CH CH2-CH3 (b) CH3CH2 CH2 CH2OH (c) CH3CH2 C- (d) Ph-C CH-CH2 Ph 17
Tertiary alcohols with two identical alkyl groups attached to the alcohol carbon can be made either from an ester and two moles of a Grignard reagent, or from a ketone and one mole of a Grignard reagent. Use retrosynthetic analysis to suggest one path of each type to synthesize 3-methyl-3-pentanol. (Click and drag the appropriate image to the correct position in the following reactions.) Tertiary alcohols with two identical alkyl groups attached to the alcohol carbon can be made either...

Show how the reaction of an allylic halide with a Grignard reagent might be used to synthesize the following hydrocarbons (draw two starting compounds; one allylic bromide and one Grignard reagent.) Make sure your Grignard is a bromide in problem. 1. 5-methylhex-1-ene 2. 2,5,5-trimethylhept-2-ene 3. 1-cyclopentylpent-2-ene
Draw the structure of the aldehyde or ketone and the Grignard reagent that will react to form the following compound: CH3 Н3С. ГОН • You do not have to consider stereochemistry • In cases where there is more than one answer, just give one. • Draw the Grignard reagent as a covalent magnesium bromide. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right comer. • Separate multiple reactants using the + sign...
