Question

Grignard reagent are formed by the reaction of alkyl halides by warming ____________. *
with alcoholic solution
with MgCl₂
Mg in presence of dry ether
with MgCO₃

Answer 1

Answer:

Grignard reagent are formed by the reaction of alkyl halides by warming Mg in the presence of dr ether .

Answer 2

Answer:

Correct option is : Mg in presence of dry ether

Explanation:

• Grignard reagent was first synthesized by the French chemist Victor grignard. It is an organomagnesium compound and is highly reactive in nature.

The chemical formula of Grignard reagent is: R-Mg-X

         Here, R = Alkyl or aryl group

         Mg = Magnesium

          X  = Halogen (Cl, Br etc)

• Grignard reagent is prepared by the reaction of alkyl or aryl halide in the presence of Magnesium and dry ether. Dry ether acts as a solvent which assists in the stabilisation of the organomagnesium compound.
