A) I < IV < II < III
B) I < II < III < IV
C) III < II < I < IV
D) IV < III < II < I
Correct Answer: A
Solution :
Reactivity towards anionic polymerisation increases as the stability of the intermediate carbanion increases. \[BC{{H}_{2}}-\overline{C}H-C{{H}_{3}}<BC{{H}_{2}}-\overline{C}H-{{C}_{6}}{{H}_{5}}<BC{{H}_{2}}\] \[-\overline{C}{{F}_{2}}<BC{{H}_{2}}-\overline{C}H-CN\] where B is any nucleophile or the base, therefore reactivity of the corresponding alkenes towards anionic polymerisation increases in the same order \[\underset{I}{\mathop{C{{H}_{2}}=CHC{{H}_{3}}}}\,<\underset{IV}{\mathop{C{{H}_{2}}=CH{{C}_{6}}{{H}_{5}}}}\,<\underset{II}{\mathop{C{{H}_{2}}=C{{F}_{2}}}}\,\] \[<\underset{III}{\mathop{C{{H}_{2}}=CHCN}}\,\]You need to login to perform this action.
