Vedclass · Answer

(C) Cationic polymerization is initiated by the formation of a carbocation intermediate. Therefore,the alkene that forms the most stable carbocation will be the most reactive towards cationic polymerization. In $CH_2 = CH - C_6H_5$ (styrene),the carbocation formed is $CH_3 - CH^+ - C_6H_5$,which is highly stabilized by resonance with the phenyl group. In contrast,the other options contain electron-withdrawing groups (like $-Cl$ or $-COOCH_3$) or only weak electron-donating groups (like $-CH_3$),which do not stabilize the carbocation as effectively as the phenyl group.
