Polymerization involves various mechanisms depending upon the initiator. If initiator generates free radical, addition polymerization takes place through free radical mechanisms. If `H^(+)` is initiator and electron releasing group is present, cationic polymerization takes place. IF electron withdrawing group is present and `KNH_(3)` is initiator, anionic polymerization takes place.
Which of the following will undergo cationic polymerization in presence of `H^(+)`

A

`CH_(2)= underset(Cl)underset(|)(CH)`

B

`CH_(2) = underset(CN)underset(|)(CH)`

C

`CH_(2)=CH_(2)`

D

`CH_(2) = underset(CH_(3))underset(|)(CH)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(2) = underset(CH_(3))underset(|)(CH)`
