Which of the following statements is not correct? a)Caprolactum is the...
Explanation:
The correct answer is option 'A' - Caprolactum is not the monomer of nylon-6.
A) Caprolactam is the monomer of nylon-6:
- Nylon-6 is a synthetic polymer that belongs to the family of polyamides.
- It is formed by the polymerization of a cyclic amide called caprolactam.
- The monomer caprolactam consists of a six-carbon ring with an amine group (NH2) and a carbonyl group (C=O) attached to it.
- When caprolactam undergoes polymerization, the amine group of one caprolactam molecule reacts with the carbonyl group of another caprolactam molecule, forming a long chain polymer.
B) Terylene is a polyester polymer:
- Terylene is a type of polyester that is commonly used in the production of fabrics and fibers.
- It is a condensation polymer formed by the reaction between ethylene glycol and terephthalic acid.
- The repeating unit in terylene consists of an ester group (-COO-) linking two aromatic rings.
C) Phenol formaldehyde resin is known as bakelite:
- Bakelite is a type of thermosetting plastic that was the first synthetic plastic to be produced on a large scale.
- It is formed by the condensation reaction between phenol and formaldehyde.
- The resulting polymer is a cross-linked network structure that is rigid, heat-resistant, and electrically insulating.
D) HDPE is a linear polymer:
- HDPE stands for High-Density Polyethylene, which is a type of thermoplastic polymer.
- It is a linear polymer formed by the addition polymerization of ethylene monomers.
- The polymer chains in HDPE have a high degree of crystallinity, which gives the material its strength, rigidity, and resistance to heat and chemicals.
Conclusion:
To summarize, the statement that is not correct is option 'A' - Caprolactam is not the monomer of nylon-6. The correct monomer for nylon-6 is caprolactum.
