Chain transfer reagent is
Options
- A(\mathrm{CCl}_4)
- B(\mathrm{CH}_4)
- C(\mathrm{O}_2)
- D(\mathrm{H}_2)
Correct answer
A. (\mathrm{CCl}_4)
Step-by-step solution
A substance that is able to cause a chain transfer in a chain polymerisation is called a chain transfer agent. It gives an atom to the radical at the growing end of a polymer chain and in doing so it results into a radical which can start the growth of a new chain. (\mathrm{CCl}_4) is a chain transfer reagent.
