Vedclass · Answer

(C) Synthetic rubbers are polymers that exhibit rubber-like properties and are prepared artificially.$(i)$ Terylene is a polyester fiber.$(ii)$ Buna$-S$ is a copolymer of $1,3$-butadiene and styrene, which is a synthetic rubber.$(iii)$ Buna$-N$ is a copolymer of $1,3$-butadiene and acrylonitrile, which is a synthetic rubber.$(iv)$ Neoprene is a polymer of chloroprene ($2$-chloro-$1,3$-butadiene), which is a synthetic rubber.$(v)$ Polyacrylonitrile is a synthetic fiber (Orlon).Therefore, $(ii)$, $(iii)$, and $(iv)$ are synthetic rubbers.Hence, the correct option is $(c)$.

List-$I$ (Polymer)	List-$II$ (Used for items)
$A$. $Nylon\,6,6$	$I$. $Bristles\,of\,brushes$
$B$. $Low\,density\,polythene$	$II$. $Toys$
$C$. $High\,density\,polythene$	$III$. $Buckets$
$D$. $Teflon$	$IV$. $Non-stick\,utensils$

Which of the following are synthetic rubbers?
$(i)$ Terylene
$(ii)$ Buna$-S$
$(iii)$ Buna$-N$
$(iv)$ Neoprene
$(v)$ Polyacrylonitrile
