Grignard Reagent: A Grignard reagent is an organometallic compound consisting of an alkyl or aryl group bonded to a magnesium atom. Grignard reagents are widely used in organic chemistry for the synthesis of alcohols, ketones, and other compounds.
Nucleophile: A nucleophile is a species that donates an electron pair to form a covalent bond. Grignard reagents are strong nucleophiles and can react with a variety of electrophilic species.
Electrophile: An electrophile is a species that is attracted to electrons and can form a covalent bond by accepting an electron pair. Carbonyl compounds, such as aldehydes and ketones, are common electrophiles that can react with Grignard reagents.
