Molecular compounds typically have lower melting points (like 80 degrees Celsius), do not conduct electricity when melted (since they do not form ions), and can have definite crystal structures. They do not contain metals (which are characteristic of ionic compounds) and their solubility can vary, but solubility alone is not a definitive identifier without more context.
