Answer & Solution

Correct Answer

(C)

Step-by-step Solution

Detailed explanation

In the polymerisation of \(\mathrm{C}_6 \mathrm{H}_5-\mathrm{CH}=\mathrm{CH}_2\) by \(\mathrm{RLi}\), free radicals like \(\mathrm{C}_6 \mathrm{H}_5-\mathrm{CH}=\underset{\mathrm{R}}{\mathrm{CH}_2}\) and are formed. These radicals are very stable and thus the chain termination…
