If the following molecules undergo radical chlorination, which position will be more likely to be chlorinated? Add a chlorine where it belongs. tond 5. Draw a mechanism for the reaction of polymerization of chloroethylene, initiated by Ch gas and UV light. n ci

Answer 1

3. Greater the stability, lesser the reactivity.

Free-radical stabilty: Benzyl radical>allylic radical>3°>2°>1°>methyl radical

4. Radical formation order also similar to above.
