Vedclass · Answer

(D) Anionic polymerisation involves the formation of a carbanion as the active species. Alkyl lithium compounds,such as $R^-Li^+$,act as effective chain initiators because they provide a nucleophilic carbanion $(R^-)$ that attacks the monomer to initiate the polymerisation process. $BF_3$ is a Lewis acid used in cationic polymerisation,while $(CH_3CO)_2O_2$ is a peroxide used in free radical polymerisation.

In anionic polymerisation,the compound which acts as an effective chain initiator is
