Question

Write the chemical reactions for the formation of the respective Grignard reagents from the reaction of magnesium with the following organic halides: iodomethane, bromobenzene, chlorocyclohexane

Answer 1

Here are the chemical reactions for the formation of the respective Grignard reagents from the reaction of magnesium with the following organic halides:

• Iodomethane:

Mg + CH3I → CH3MgI

• Bromobenzene:

Mg + C6H5Br → C6H5MgBr

• Chloropropane:

Mg + C3H7Cl → C3H7MgCl

Grignard reagents are formed when magnesium metal is reacted with an alkyl halide. The magnesium metal reacts with the halide to form a magnesium halide salt, and the alkyl group is displaced from the halide to form the Grignard reagent.

The Grignard reagent is a powerful nucleophile and can be used to synthesize a variety of organic compounds.
