✏️ Drawing Polymer Structures
Step-by-Step Drawing Method
- Start with the monomer structure
- Remove the double bond (C=C becomes C-C)
- Add bonds going out from each end carbon (continuation lines)
- Put the structure in brackets with 'n' subscript
Common Polymer Structures
- Poly(ethene): [-CH₂-CH₂-]ₙ from H₂C=CH₂
- Poly(propene): [-CH₂-CH(CH₃)-]ₙ from H₂C=CH(CH₃)
- PVC: [-CH₂-CHCl-]ₙ from H₂C=CHCl (chloroethene)
Exam Tip: Always show the continuation lines (bonds going out of the brackets) — these show the chain continues. Also remember the 'n' subscript.
