1 PM S1 P3 analyse information from secondary sources such as computer simulations, molecular model kits or multimedia resources to model the polymerisation processanalyse information from secondary sources such as computer simulations, molecular model kits or multimedia resources to model the polymerisation process

2 Q: Justify the appropriateness of using sources such as computer simulations and molecular model kits to model the polymerisation process. (6 Marks) PM S1 P3

3 Your answer should address the following: Moly-mod kits allow 3D understanding that cannot be gained by pen and paper. They are better than computer for spatial arrangement as you can physically interact with it. Computer simulations also allow one to see the structure, spatial arrangement, bond angles, relative sizes (providing they are correctly programmed). Good because they also allow movement in 3D free from gravity. Both of these are clearly much better than pen and paper for visualising structure, bonding, rotation of bonds, chain-chain interactions etc. However relative sizes are important: Cl is 3x bigger than H but you don’t see this in the molymod kits which leads to problems in explaining properties of PVC compared to polyethylene.
