Question

Match materials given in column I with the polymers given in column II.

Column I	Column II
A. Natural rubber latex	1. Nylon
B. Wood laminates	2. Neoprene
C. Ropes and fibres	3. Dacron
D. Polyester fabric	4. Melamine formaldehyde
E. Synthetic rubber	5. Urea-formaldehyde
F. Unbreakable crockery	6. cis-polyisoprene

Answer 1

Hint: A polymer is a complex molecule made of repetitive small units called monomers. Some examples of polymers are nylon, polyester, etc. Here, some substances are given and we have to find out the polymer that made these substances.

Complete Step by Step Solution:
Natural rubber latex is a polymer whose monomer units are isoprene molecules. The polymerization of isoprene gives cis-1,4-polyisoprene(natural rubber latex). They have naturally obtained elastomers. Therefore, A matches with 6.
Let’s understand wood laminates. Wood laminates are made of a polymer whose name is urea formaldehyde. Therefore, B matches with 5.
Nylon is a polymer made of polyamides. They have very high strength. Therefore, they are used to make fibres and ropes. Therefore, C matches with 1.
Dacron is called polyester and it is formed due to the polymerization of a diacid and a diol. Therefore, D matches with 3.
Neoprene is a polymer made by the monomer named chloroprene. And neoprene is a synthetic fibre. Therefore, E matches with 2.
Unbreakable crockery is made of a polymer named melamine-formaldehyde. Therefore, F matches with 4.
Therefore, the complete table is,

Column I	Column II
A. Natural rubber latex	6. cis-polyisoprene
B. Wood laminates	5. Urea-formaldehyde
C. Ropes and fibres	1. Nylon
D. Polyester fabric	3. Dacron
E. Synthetic rubber	2. Neoprene
F. Unbreakable crockery	4. Melamine formaldehyde

Note: There are two processes by which polymers are formed. They are addition polymerization and condensation polymerization. In addition polymerization, the formation of polymers occurs due to the repetitive addition of monomers but in condensation polymerization, repetitive condensation of bi and tri-functional monomers occurs.
