Which is the best monomer for getting chain growth polymer?

View answer and explanation

Correct option: C

\mathrm{C}{\mathrm{H}_2} = \mathrm{CH}{\mathrm{C}_6}{\mathrm{H}_5}

Option C (

\mathrm{C}{\mathrm{H}_2} = \mathrm{CH}{\mathrm{C}_6}{\mathrm{H}_5}

) is correct because the presence of the phenyl group stabilizes the propagating radical, facilitating chain growth polymerization.
