Synthesis of $Buna-S$ needs nascent oxygen.

Vedclass · Answer

(A) The provided image shows the polymerization of $1,3-butadiene$ and styrene to form $Buna-S$ in the presence of nascent oxygen as an initiator. $Buna-S$ is a synthetic elastomer (a type of rubber),not a thermosetting polymer. $Neoprene$ is a homopolymer of $chloroprene$,not a copolymer. $Buna-N$ is a synthetic copolymer,not a natural polymer. Therefore,the statement that the synthesis of $Buna-S$ requires nascent oxygen is correct based on the provided reaction scheme.
