Grignard Reagent
Easychemistry
Grignard reagent is prepared by reacting alkyl halide with:
Select the correct option:
Solution
Incorrect! Answer:
Mg in dry ether
Grignard Reagents (R−MgX) are organometallic compounds of immense synthetic importance.
- Synthesis: R−X+Mgdry etherR−Mg−X
- Dry Ether Solvent: It is crucial because Grignard reagents are highly reactive toward moisture (proton sources). Ether also stabilizes the reagent by coordinating to the Magnesium atom.
- Nature: The C−Mg bond is highly polar (Cδ−−Mgδ+), making the R group a very strong nucleophile and a strong base.
