Polypropylene can be obtained by polymerisation of

A

CHCHCH \equiv CH

B

CH2=CH2CH_{2} = CH_{2}

C

CH3CH=CH2CH_{3} - CH = CH_{2}

D

CH3CCHCH_{3} - C \equiv CH

Answer

CH3CH=CH2CH_{3} - CH = CH_{2}

Explanation

Solution

nCH3PropeneCH=CH2(CH2CHCH3)nPolypropylene\underset{\text{Propene}}{nCH_{3}}–CH = CH_{2} \rightarrow \underset{\text{Polypropylene}}{( - CH_{2} - \underset{CH_{3}}{\underset{|}{CH -}})_{n}}
