Understanding Polyamides
Polyamides are a class of polymers characterized by the presence of amide linkages (-CONH-). They are known for their strength, durability, and resistance to wear and tear.
Polymers in Question
1. Nylon-6:
- A synthetic polymer made from caprolactam.
- Contains amide linkages, classifying it as a polyamide.
2. Nylon-6,6:
- Formed from hexamethylenediamine and adipic acid.
- Also contains amide linkages, making it another example of a polyamide.
3. Polyvinyl Chloride (PVC):
- A widely used plastic made from vinyl chloride monomer.
- It does not contain amide linkages and is not classified as a polyamide.
4. Polystyrene:
- A polymer made from the monomer styrene.
- Lacks amide linkages and is not classified as a polyamide.
Correct Answer Explanation
- The correct answer is option 'B' (Nylon-6 and Nylon-6,6).
- Both Nylon-6 and Nylon-6,6 are polyamides due to their amide linkages.
- Polyvinyl chloride and polystyrene do not fit into the polyamide category because they lack these linkages.
Summary
In conclusion, the only polymers that are classified as polyamides from the given options are Nylon-6 and Nylon-6,6. PVC and polystyrene do not meet the criteria for polyamides, thus reinforcing that option 'B' is the correct choice.
