Question

The metal used in preparation of Grignard reagent is ______.

Options

• Al

• Mg

• Na

• Fe

Answer 1

The metal used in preparation of Grignard reagent is Mg.

Explanation:

Grignard reagents are organomagnesium compounds with the general formula R–Mg–X, where R is an alkyl or aryl group, and X is a halogen. They are prepared by reacting an alkyl or aryl halide with magnesium metal in the presence of an anhydrous solvent like dry ether. During this reaction, the magnesium atom inserts itself between the carbon and the halogen atom to form the reagent.
