- D (i), (ii) and (iv)
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…
