6Intermolecular Forces Physical PropertiesMedium1 mark
Materials can be classified by their chemical structures. The four types of structure are metallic, ionic, simple molecular and giant molecular.
A, B, C and D all have different types of structure.
Which substance has a simple molecular structure?
| melting point / C | effect of adding water | electrical conductivity | |
|---|---|---|---|
| A | 64 | reacts | good when solid |
| B | 113 | insoluble | always poor |
| C | 767 | soluble | good when solid |
| D | 1600 | insoluble | always poor |
