Vedclass · Answer

(D) The correct matches are as follows:$A$. Acrilan (Polyacrylonitrile) has the repeating unit $-[CH_2-CH(CN)]_n-$ $(iv)$.$B$. Polystyrene is formed from styrene,so its repeating unit is $-[CH_2-CH(C_6H_5)]_n-$ $(ii)$.$C$. Neoprene is polychloroprene,with the repeating unit $-[CH_2-C(Cl)=CH-CH_2]_n-$ $(iii)$.$D$. Novolac is a linear polymer of phenol and formaldehyde $(v)$.$E$. Buna-$N$ is a copolymer of $1,3$-butadiene and acrylonitrile,with the repeating unit $-[CH_2-CH=CH-CH_2-CH_2-CH(CN)]_n-$ $(i)$.Therefore,the correct match is $A-iv, B-ii, C-iii, D-v, E-i$.

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
