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
The nucleophilic reaction that consists of bimolecular as well as bond-making and bond-breaking steps is termed as
