Question

Identify the type of polymer. $(i) ?$(ii) ?? ?

• A. (i) Homopolymer, (ii) Copolymer
• B. (i) Natural polymer, (ii) Synthetic polymer
• C. (i) Linear polymer, (ii) Branched polymer
• D. (i) Fibre, (ii) Elastomer

Answer 1

Answer: (A)

(i) Homopolymer, (ii) Copolymer

Answer 2

Homopolymer - If only one type of monomeric unit takes part to form a polymeric structure, it is called as a homopolymer. Example = Glycogen, starch, chitin Since (i) is made up of only A type of monomer, it is a homopolymer Copolymer - If two types of monomeric units take part to form a polymeric structure, it is called as a copolymer. Example = Nylon $6-6$, dacron, glyptal Since (ii) is made up of $A$ and $B$ type of monomer, it is a copolymer.
