Which from following polymers is obtained by condensation polymerisation method ?
Options
- A[ , CF ₂ - CF ₂ ,]_n
- B[ , CH ₂ - CH ₂ ,]_n
- C[ , NH - ( CH ₂)₅ - CO ,]_n
Correct answer
3
Step-by-step solution
To determine which polymer is obtained by condensation polymerisation, let us analyze each option: 1. [ , CF ₂ - CF ₂ ,]_n is Teflon (Polytetrafluoroethylene). It is formed by the addition polymerisation of tetrafluoroethene. 2. [ , CH ₂ - CH ₂ ,]_n is Polythene. It is formed by the addition polymerisation of ethene. 3. [ , NH - ( CH ₂)₅ - CO ,]_n is Nylon 6. It is synthesized by the ring-opening polymerisation of caprolactam. Since no small molecule is eliminated during the process, it is technically considered an
