Question

Chain transfer reagent is

• A. $CCI_4$
• B. $CH_4$
• C. $O_2$
• D. $H_2$

Answer 1

Answer: (A)

$CCI_4$

Answer 2

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. $CCl_4$ is a chain transfer reagent.
