Question

In a Grignard reagent, the bond between carbon and magnesium atoms is covalent, but highly polarized. Select the appropriate word or phrase that completes the sentences about the character of this carbon atom. The magnesium-bound carbon of a Grignard reagent reacts as if it is a ________. This carbon atom is a __________ and also an excellent ________.

Answer 1

Answer:

Carbanion , strong base, nucleophile

Explanation:

• The Grignard’s carbon atom has a negative charge that means it is a carbanion.

• In Grignard reagents, the carbon reacts as it is a powerful base and reacts with acidic hydrogen (like alcohol, etc.)

• They are good nucleophiles and react with carbonyl compounds due to the attraction between partial negative charge of Grignard’s carbon atom and positive charge of carbon of carbonyl compound.
