What is the role of Mg metal in the Grignard reaction?

A) Removing excess hydrochloric acid
B) To liberate benzhydrol
C) Holding water
D) Creating the Grignard reagent
E) Catalyst

Answer :

The role of Mg metal in the Grignard reaction is to create the Grignard reagent, which is a highly reactive compound used for various chemical reactions. Hence the correct option is option d) Creating the Grignard reagent

The role of Mg metal in the Grignard reaction is to create the Grignard reagent. The Grignard reagent is formed by reacting an organic halide with magnesium metal in the presence of anhydrous ether. This reaction forms a carbon-magnesium bond, which is highly reactive and can be used for various chemical reactions.

The Grignard reagent is a versatile compound that can be used to synthesize alcohols, acids, and many other organic compounds. It acts as a nucleophile, attacking electrophilic carbonyl compounds and forming new carbon-carbon bonds.

In summary, the Mg metal is essential in the Grignard reaction as it serves as the reagent's source of the carbon anion and allows for the creation of the Grignard reagent.
