Question

Match the column.
List - I List - II
A) Rayon 1) Cationic Polymerisation
B) Glass 2) Organic Polymers
C) Polystyrene 3) Inorganic polymers
D) Polyisoprene 4) Anionic polymerisation

• A. $A-2,B-3,C-4,D-1$
• B. $A-3,B-2,C-4,D-1$
• C. $A-2,B-1,C-3,D-4$
• D. $A-2,B-3,C-1,D-4$

Answer 1

The correct option is D $A-2,B-3,C-1,D-4$

$Rayon$ is long cellulosic chain polymer. Glass is a silicate structure formed by $Si-O-Si$ linkage.
$Polystyrene$ is best prepared by cationic polymerization because the monomer forms resonance stabilised monomer intermediate.
$Polyisoprene$ is prepared by anionic mechanism because $-Cl$ shows $-Ieffect$.
Hence, the correct match is $A-2,B-3,C-1,D-4$.
