Interpretation:
A product of the given reaction has to be suggested.
Concept Introduction:
Grignard Reaction: This is a organometallic reaction in different alkyl, aryl-magnesium halides add to a carbonyl group in an
Alkyl or aryl magnesium halides (
Synthesis of Grignard reagent is shown below,
Nucleophiles: A nucleophile is a more reactant species that affords a pair of electrons to the electrophile or electrophilic center and forms a new covalent bond. The carbon or other hetero atom in a molecule which is bearing negative charge or lone pair of electron is called as nucleophiles.
