Interpretation: The reason corresponding to the fact that organolithium reagents are not used to generate enolates is to be stated.
Concept Introduction: The substitution reaction involves the replacement of one functional group by other functional group. In nucleophilic substitution an electron rich species attack the species that is deficient in electrons. The electrophile and the leaving group together form a substrate. The nucleophile attacks over the substrate and there occurs the removal of leaving group from the substrate.
The nucleophilic reaction that consists of bimolecular as well as bond-making and bond-breaking steps is termed as

- Why is it not advisable to use aqueous hydrochloric acid in a Grignard reaction of a ketone? A) The Grignard reagent will react with the acid and cannot react with the ketone. B) The ketone will be protonated and will become unreactive. C) The ketone will form an unreactive enol.
