Rank the following monomers in order of increasing reactivity toward anionic polymerization (least reactive to most reactive).

Question

Quizplus · Accepted Answer

Anionic polymerization involves initiation with a strong base, which attacks the double bond of the monomer. The reactivity of the monomer is determined by its electron-donating or withdrawing groups, which affect the stability of the intermediate anion. Monomers with electron-withdrawing groups are more reactive, while those with electron-donating groups are less reactive. Therefore, the order of decreasing reactivity is I, IV, III, II. So, the correct option is C: I, IV, III, II.
