Match List I and List II

(i)-(c); (ii)-(a); (iii)-(b); (iv)-(e); (v)-(d)

The correct answer is option 4.(i)-(c); (ii)-(a); (iii)-(b); (iv)-(e); (v)-(d)

Let us match each polymer from List I to its correct description in List II:

(i) Nylon 6 - (c) Polycaprolactam:

Nylon 6 is a synthetic polymer also known as polycaprolactam. It is produced through the ring-opening polymerization of caprolactam, a lactam (a cyclic amide). Nylon 6 is known for its strength, elasticity, and resistance to abrasion and chemicals, making it widely used in textiles and engineering plastics.

(ii) PVC - (a) Polyvinyl chloride:

PVC stands for polyvinyl chloride. It is a polymer made from the polymerization of vinyl chloride monomers. PVC is a versatile plastic used in construction (pipes, window frames), medical devices (blood bags, tubing), and various everyday products (credit cards, flooring).

(iii) Acrilin - (b) Polyacrylonitrile:

Acrilin refers to polyacrylonitrile (PAN). Polyacrylonitrile is a polymer made from the polymerization of acrylonitrile monomers. It is used as a precursor for carbon fibers, in synthetic fibers (like Orlon), and in applications requiring high chemical and thermal stability.

(iv) Natural rubber - (e) cis-Polyisoprene:

Natural rubber is primarily composed of cis-1,4-polyisoprene. This natural polymer is obtained from the latex of rubber trees (Hevea brasiliensis). It has high elasticity, resilience, and tensile strength, making it ideal for products like tires, footwear, and elastic bands.

(v) LDP - (d) Low Density Polyethene:

LDP stands for low-density polyethylene. It is produced through the polymerization of ethylene monomers at high pressures and temperatures, resulting in a polymer with a branched structure. This branching makes LDP more flexible and less dense than high-density polyethylene (HDPE). LDP is used in packaging films, plastic bags, containers, and tubing.

The correct option is:4.  (i)-(c); (ii)-(a); (iii)-(b); (iv)-(e); (v)-(d)
