In which of the following chain termination step is absent?
- A Polymerisation of \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}=\mathrm{CH}_2\) by \(\mathrm{RLi}\)
- B Polymerisation of \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}=\mathrm{CH}_2\) by \(\mathrm{BF}_3\) and \(\mathrm{H}_2 \mathrm{O}\)
- D Polymerisation of \(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}=\mathrm{CH}_2\) by \(\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{COO}\right)_2\)
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…
