Question

In a Grignard reagent, the carbon bonded to the magnesium has a partial ________ charge, because carbon is ________ electronegative than magnesium. This makes this carbon of the Grignard ________. In a Grignard reagent, the carbon bonded to the magnesium has a partial ________ charge, because carbon is ________ electronegative than magnesium. This makes this carbon of the Grignard ________. negative, less, electrophilic positive, less, electrophilic positive, more, electrophilic negative, more, nucleophilic positive, less, nucleophilic

Answer 1

In a Grignard reagent, the carbon bonded to the magnesium has a partial negative charge, because carbon is more electronegative than magnesium. This makes this carbon of the Grignard nucleophilic In a Grignard reagent, the carbon bonded to the magnesium has a partial positive charge, because carbon is more electronegative than magnesium. This makes this carbon of the Grignard less electrophilic.

Step-by-step explanation:

The Grignard reagent is a highly reactive organomagnesium compound formed by the reaction of a haloalkane with magnesium in an ether solvent. The carbon atom of a Grignard reagent has a partial negative charge. Hence a Grignard reagent will have a general formula RMgX. Where R must contain a carbanion.

Grignard reagents are versatile reagents used in many applications in organic chemistry.

Answer 2

In a Grignard reagent, the carbon bonded to the magnesium has a partial negative charge, because carbon is more electronegative than magnesium. This makes this carbon of the Grignard nucleophilic.

Step-by-step explanation:

Organometallic compounds have covalent bonds between carbon atoms and metallic atoms. Organometallic reagents are useful because they have nucleophilic carbon atoms, in contrast to the electrophilic carbon atoms of the alkyl halides. The majority of metals are more electropositive than carbon, and the bond is biased with a positive partial charge on the metal and a negative partial charge on the carbon.
