JEE PYQ: Biomolecules And Polymers Question 49
Question 49 - 2019 (12 Apr Shift 2)
The correct name of the following polymer is:
[Structure shows isobutylene polymer with $\text{H}_3\text{C}$ and $\text{CH}_3$ groups]
(1) Polyisobutane
(2) Polytert-butylene
(3) Polyisoprene
(4) Polyisobutylene
Show Answer
Answer: (4)
Solution
$\text{CH}_3-\text{C}=\text{CH}_2 \xrightarrow{\text{Polymerisation}}$ Polyisobutylene. The structure with $\text{H}_3\text{C}$ and $\text{CH}_3$ on the same carbon is polyisobutylene.
