The preparation of the reagents that will be made theoretically requires equivalent amounts of the organic halide and magnesium, but slightly of the magnesium is normally used.

The preparation of the reagents that will be made theoretically requires equivalent amounts of the organic halide and magnesium , but slightly Grignard reagent of the magnesium is normally used.

Explanation:

When the metal is binded to a carbon atom in an alkyl group a Grignard reagent is formed. An alkyl group contains a carbon and a hydrogen atom. Bromine and Iodine are the most common halogen atoms used during their reactivity. The magnesium is coated with a layer of magnesium oxide which inhibits reactions with the organic halide. The Grignard reaction is often used as a initiator.

The reaction starts with hydrocarbyl halide, based on organic history it is a big deal in the number of C - C bond forming reactions is very small, and Grignard reaction is the best and most effective reactions.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
