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-$I$ (Monomer Unit)	List-$II$ (Polymer)
$(a)$ Caprolactum	$(i)$ Natural rubber
$(b)$ $2-$Chloro$-1,3-$butadiene	$(ii)$ Buna$-N$
$(c)$ Isoprene	$(iii)$ Nylon$-6$
$(d)$ Acrylonitrile	$(iv)$ Neoprene

Column-$I$	Column-$II$
$A$. Acrilan	$i$. $-[CH_2-CH(CN)]_n-$
$B$. Polystyrene	$ii$. $-[CH_2-CH(C_6H_5)]_n-$
$C$. Neoprene	$iii$. $-[CH_2-C(Cl)=CH-CH_2]_n-$
$D$. Novolac	$iv$. $-[CH_2-CH=CH-CH_2-CH_2-CH(CN)]_n-$
$E$. Buna-$N$	$v$. Linear phenol-formaldehyde polymer

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