1. Compound description ionic or molecular? 1 Compound 1 is a hard white smooth odorless solid, which is insoluble in water. If the flame from an ordinary laboratory burner is held on the solid for 10 minutes, the solid grows hot to the touch but does not soften. ionic molecular (can't decide)
2 Compound 2 is a hard light gray solid made up of clusters of cube-shaped crystals. It can easily be ground into a fine powder. If that powder is compressed to form a block, the block is an insulator. However, if the block is moistened slightly, it starts to conduct electricity much better. ionic molecular (can't decide)
3 Compound 3 is a clear liquid with a strong pleasantly fruity smell. If cooled it freezes at about −10°C. In the solid state it does not conduct electricity. ionic molecular (can't decide)
