Question 28
Which polymer is not hydrolysed when heated with aqueous alkali? A Kevlar B Nylon 6.6 C Poly(propene) D Terylene
Worked Solution & Example Answer:Which polymer is not hydrolysed when heated with aqueous alkali? A Kevlar B Nylon 6.6 C Poly(propene) D Terylene - AQA - A-Level Chemistry - Question 28 - 2022 - Paper 3
Step 1
C Poly(propene)
Answer
Poly(propene), also known as polypropylene, is a non-polar polymer that does not undergo hydrolysis when treated with aqueous alkali. This property distinguishes it from other types of polymers like Kevlar, Nylon 6.6, and Terylene, which are susceptible to hydrolysis under alkaline conditions.
