Show answer
Correct Option: A

Which of the following alkenes is most reactive towards cationic polymerization?

chemistry petrochemicals and polymers addition polymerisation types of polymerisation reactions polymer

  1. ${ CH } _{ 2 }$ = ${ CHCH } _{ 3 }$

  2. ${ CH } _{ 2 }$ = $CHCl$

  3. ${ CH } _{ 2 }$ = ${ CHC } _{ 6 }{ H } _{ 5 }$

  4. ${ CH } _{ 2 }$ = ${ CHCOOCH } _{ 3 }$

Show answer
Correct Option: C
Explanation:

In cationic polymerization the most stable cation will show the highest reactivity.

The order of reactivity will be-

$CH _2 = CH-C _6H _5 > CH _2  = CHCH _3 > CH _2 = CHCl >CH _2 = CHCOOCH _3$

Option C is correct.
