Polymers Question 34

Question: Polypropylene can be obtained by polymerisation of

Options:

A) $ CH\equiv CH $

B) $ CH_2=CH_2 $

C) $ CH_3-CH=CH_2 $

D) $ CH_3-C\equiv CH $

Show Answer

Answer:

Correct Answer: C

Solution:

$ \underset{Propene}{\mathop{nCH_3}}CH=CH_2\to \underset{Polypropylene}{\mathop{{{(-CH_2-\underset{CH_3}{\mathop{\underset{|}{\mathop{CH-}}}})} _{n}}}} $
