Question

Which type of bond present between carbon and magnesium in grignard reagent?

Answer 1

A covalent bond is present between carbon and magnesium in the grignard reagent.

• The chemical formula of the Grignard reagent is $CH_3MgBr$.
• This is an organometallic compound of the p block element.
• Here a covalent bond is present between carbon and magnesium.
• The covalent bond is a 2c-2e bond and it is polarized in nature.
• So, the bond between carbon and magnesium is a 2c-2e pure covalent bond.

Answer 2

A covalent bond present between carbon and magnesium in grignard reagent.

Explanation:

• Grignard reagent has the chemical formula $CH3MgX$
• It is an organometallic compound of the p block element with the halogen associated to it.
• A covalent bond is present between carbon and magnesium.
• The reagent has polar carbon magnesium bond where the carbon atom will acquire a partial negative charge and the metal a partial positive charge.
• The covalent bond is between the 2c-2e bond and which gets polarized in nature.
• So, the bond between carbon and magnesium is a 2c-2e pure covalent bond.
• The carbon–halogen bond of haloalkanes is opposite that of the polarity of the carbon–magnesium bond.
