Hint:. Polymers are those compounds in which the repeating units are very large in number. The polymer that must be used in the covering of electric wire must be rigid and flexible. The pans are made up of Polytetrafluoroethylene.
Complete step by step answer:
- The K polymer says it is used for the coating of electric wires, so PVC or polyvinyl chloride is used for the coating of the electric wires. The monomer unit for the PVC is Vinyl chloride whose formula is $C{{H}_{2}}=CH-Cl$. It is also used for making raincoats, handbags, shower curtains, vinyl flooring, etc.
- The L polymer says that it is used as a non-stick coating on cookware, so Teflon is used in non-stick utensils. The monomer unit for Teflon is Tetrafluoroethene whose formula is ${{F}_{2}}C=C{{F}_{2}}$. It is used in the utensils because it is chemically very inert and has high thermal stability. It is also used in making gaskets, seals, valves, etc.
- The P polymer says it is used for the coating of the uniform of firemen, so melamine is used in the coating of the uniforms of the firemen. The IUPAC name of melamine is 2, 4, 6-Triamino-1, 3, 5-triazine. The melamine is usually used for making non-breakable plastic crockery.
- The Q polymer says it is used for making electrical switches and handles of the utensils, so Bakelite is used for this purpose. Initially, the Bakelite is made from phenol and formaldehyde, forming novolac which is the monomer of Bakelite. It is also used for making photograph records, computer discs, etc.
So, the correct answer is “Option D”.
Note: PVC and Teflon are examples of additional polymerization in which there is no loss of any molecule during polymerization. Melamine and Bakelite are examples of condensation polymerization in which small molecules like water are eliminated during polymerization.
