Draw the mechanism of reaction with every single step, with the proper explanation of each step.

Answer 1

Preparation of Grignard Reagent Grignard reagents also called organometallic compound can be formed through the reaction of an alkyl or aryl halide with magnesium metal. This reaction is proceeded by adding the organic halide to a suspension of magnesium in an ether (the solvent, which Provides ligand required to stablize the organomenag organomagnesium Compound. Empirical evidence reveals that the reaction takes place on the surface of the metal. The reaction proceeds via single electron transfor. In the Grignard formation reaction, radicals may be converted into Carbanions through a second electron transfer. Mg Br THE [ mg
