Formation of Grignard reagent from an alkyl halide and Mg metal takes place in _?
Correct answer: C. Anhydrous ether
- A. Water
- B. Alcohol
- C. Anhydrous ether
- D. Carbon tetrachloride
Explanation
OPTIONS A, B: Water and alcohol would react with the Grignard reagent, leading to its destruction and preventing its formation.OPTION C: The formation of Grignard reagent from an alkyl halide and magnesium metal takes place in anhydrous ether. Anhydrous ether is used as the solvent because it is non-polar and does not react with the Grignard reagent, allowing it to be formed and maintained in its reactive form.OPTION D: Carbon tetrachloride is not commonly used as a solvent for Grignard reactions as it is toxic and has been largely replaced by other solvents, such as anhydrous ether.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
