Not in JEE Main or NEET syllabus
Arrange the following monomers in order of decreasing ability to undergo cationic polymerisation.
I. II. III.
Answer: (B)
Solution
Cationic polymerization proceeds through a benzylic carbocation on the vinyl-substituted benzene ring, which is stabilized by electron-releasing ring substituents and destabilized by electron-withdrawing ones. The methoxy group (–OCH, monomer III) is the strongest electron donor by resonance,
