Question

Formation of Grignard's Reagents




​

Answer 1

Answer:

Grignard reagents are formed by the reaction of magnesium metal with alkyl or alkenyl halides. They're extremely good nucleophiles, reacting with electrophiles such as carbonyl compounds (aldehydes, ketones, esters, carbon dioxide, etc) and epoxides

Explanation:

Answer 2

The grignard's reagent is prepared by the reaction of orgnaic halides (R-X) and magnesium metal (Mg).

Explanation:

• Grignard's reagent is a organometallic compound, it has magnesium metal.
• It is generally represented as RMgX, where R can be alkyl or aryl part, and X is the halogen.
• It is prepared from magnesium (Mg) and organic halide (R-X) reaction in the presence of ether (ethyl ether) in inert medium as water and air cause it to decompose.
• It follows the free radical mechanism.
• The reactions of its preparation is shown as:
