Grignard reagent is produced by the reaction of alkyl halides with _?
Correct answer: B. Mg in dry ether
- A. Ca in anhydrous ether
- B. Mg in dry ether
- C. Mg in moist ether
- D. Ca in dry ether
Explanation
Grignard reagents are produced by the reaction of alkyl halides with magnesium (Mg) in dry ether. The correct option is B. Dry ether is essential to prevent interference from water, which can react with the Grignard reagent. Calcium (Ca) is not typically used in the preparation of Grignard reagents.

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.
