Free radical polymerization of stryene gives a product in which groups are on alternate carbon atoms rather than on adjacent carbon atoms. Exlpain. |
Answer» SOLUTION :During free radical polymerization , the ADDITION of free radicals to monomer molecules occurs in accrodance with Markovnikov's rule so as to give more stable free radical. For example , addition of R. (obtained from radical initiator) to styrene GIVES more stable BENZYLIC radical (I) rather than less stable radical (II).  The free radical (I) then adds to another monomer molecule again giving a more stable free radical (III) rather than the less stable free radical (IV). This process continues to give ultimately polystyrene (V) in whicyh the `C_6H_5` groups are on alternate carbon atoms rather than the product (VI) in which the `C_6H_5` groups are on adjacent carbon atoms.
