Interpretation: Among the given alky halides, the one that could be successfully used to prepare a Grignard reagent have to be found.
Concept Introduction:
Grignard reagent: Alkyl, vinyl, or aryl-magnesium halides are called as Grignard reagents.
The chemical formula of the Grignard reagent is
Grignard reagents are very good nucleophiles and the alkyl group in it act as if it is a carbanion. So the alkyl part remains as nucleophilic part of the Grignard reagent whereas the metallic magnesium part remains as electrophilic part of it.
Grignard reagent preparation:
Example:
The given reaction is the preparation of Grignard reagent by treating
