Questions: Atoms, Ions and Molecules In the table below, there are descriptions of an experiment on samples of three different chemical compounds. Decide whether the compound is ionic or molecular, if you can. If there is not enough information to decide, choose can't decide in the third column. compound description ionic or molecular? --------- 1 Compound 1 is a clear liquid with a strong smell. If heated gently it boils at 115 °C. Onic 2 Compound 2 is a dull white smooth solid which does not conduct electricity. Applying an ordinary laboratory burner to the material only makes the substance hot, it does not otherwise change. In fact, the substance can't be melted or even softened by any ordinary laboratory equipment. (can't decide) 3 Compound 3 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. O molecular
