Verified Solution

Answer & Solution

Correct Answer

(C) (ii), (iii) and (iv)

Step-by-step Solution

Detailed explanation

\(\because\) Buna-S is \(n \mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_2\) \((1,3\)-butadine \()+n \mathrm{C}_6 \mathrm{H}_5-\mathrm{CH}=\mathrm{CH}_2\) (styrene); Buna- \(\mathrm{N}\) is \(n \mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}_2\) All these are synthetic…
