JEE PYQ: Biomolecules And Polymers Question 51
Question 51 - 2019 (09 Jan Shift 1)
Major product of the following reaction is:
[Methacryloyl chloride + $\text{H}_2\text{N}-\text{CH}_2\text{CH}_2\text{CONH}_2$ $\xrightarrow{(1) \text{Et}_3\text{N}}$ $\xrightarrow{(2) \text{Free radical polymerisation}}$]
(1) Polyamide with pendant amide group
(2) Polyamide with pendant chloride
(3) Polyamide with cyclic imide
(4) Polyamide with different connectivity
Show Answer
Answer: (4)
Solution
The methacryloyl chloride reacts with the amine via $\text{Et}_3\text{N}$ to form an amide linkage, then free radical polymerisation occurs through the vinyl group.
