How to Make a Grignard's Reagent?

What is Grignard's reagent made from?

A. Methyl amine

B. Diethyl ether

C. Ethyl iodide

D. Ethyl alcohol

Correct answer is D

Answer:

Grignard's reagent is made by reacting magnesium with ethyl alcohol (option D).

Grignard's reagent is a very useful compound in organic chemistry. It is typically made by reacting magnesium metal with an organic halide compound, such as ethyl alcohol in this case. The reaction between magnesium and ethyl alcohol leads to the formation of an alkyl magnesium halide compound, which is known as a Grignard's reagent.

The formation of Grignard's reagent is a key step in many organic synthesis reactions. It is widely used to introduce alkyl, vinyl, or aryl groups into organic molecules. The high reactivity of Grignard's reagents makes them valuable intermediates in organic chemistry.

To make a Grignard's reagent, it is important to carry out the reaction under anhydrous conditions to prevent the formation of unwanted side products. The reaction is usually performed in an inert atmosphere, such as nitrogen or argon, to avoid any reactions with moisture or oxygen in the air.

In conclusion, Grignard's reagent is made by reacting magnesium with ethyl alcohol, leading to the formation of an alkyl magnesium halide compound that is widely used in organic synthesis reactions.
