polymers are long chains of repeating units
polymers have strong covalent bonds
intermolecular forces between polymers are larger than the ones in simple covalent molecules
most polymers are solid at room temperature
intermolecular forces are weaker than ionic or giant molecular compounds so have a lower bp
giant covalent structures
- all atoms bonded by covalent bonds
- high mp and bp
- dont conduct electricity (except graphite)
diamond- 4 covalent bonds in a rigid structure
graphite- three covalent bonds and 1 delocalised electron. layers of hexagons
