Which of the following statements is false?
Which of the following statements is false?
Updated On: Apr 28, 2025
- Nylon-66 is an example of elastomer.
- The repeat unit in natural rubber is isoprene.
- Both starch and cellulose are polymers of glucose.
- Artificial silk is derived from cellulose.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Nylon-66 is not an elastomer; it is a synthetic polymer that belongs to the class of polyamides. Elastomers are polymers that possess rubber-like elasticity, such as natural rubber or synthetic rubbers like polyisoprene.
So, the correct option is (A): Nylon-66 is an example of elastomer.

- Polypropene is formed by the repetitive joining of propene. Propene is the monomer of Polypropene. It is used in the preparation of different materials like fibres, ropes, pipes etc.
- Polystyrene is formed from aromatic hydrocarbons, styrene is its monomer. It is used as a wrapping material to provide coverage to important materials, cabinets of television, in making radios.
- Polyvinyl Chloride (PVC) is formed by combining a large number of molecules of vinyl chloride. Vinyl chloride is its monomer. It is used in making raincoats and especially in water pipes.
- Glyptal is a synthetic polymer that is formed by monomers of Ethylene glycol and Phthalic acid. It is used in the manufacturing of paints, fabrics, lacquers etc.
- Bakelite is known as Polyoxybenzylmethylenglycolanhydride. Phenol and Formaldehyde are used as monomers to produce bakelite which is formed by the condensation reaction of these monomers.
- Natural Rubber is composed of polyisoprene molecules linked together to form an elastomeric structure. Natural rubber is used for various purposes like making tyres, rubber bands, lid grippers etc.
- Polypropylene is a hydrocarbon polymer that has a linear structure. It is a multifaceted polymer as it has properties of plastic as well as fibre and hence is used for multi-purposes. Propylene is the monomer of polypropylene.
- Polyethylene Terephthalate also termed PET is a thermoplastic polymer. Ethylene glycol and terephthalic acid are used in the preparation of Polyethylene Terephthalate and in making different things like containers for packing food and drinks.
- Polytetrafluoroethylene also termed PTFE is a fluoropolymer. It is slippery in nature and is highly resistant to heat. The monomer of polytetrafluoroethylene is tetrafluoroethylene.
Neoprene is formed from chloroprene. It is prepared by free radical polymerisation. The monomer of neoprene is chloroprene. It is used for preparing gaskets, conveyor belts etc.
