WebJan 2, 2012 · Organic compounds can be gases, liquids, or solids at room temperature. Ionic compounds are all solids at room temperature with very high melting points. Organic compounds have relatively low melting points and boiling points. The reason for these differences lies in the type of attractive forces holding the particles next to each other in … Weban accurate boiling-point value, the liquid should be distilled rapidly. 3. Solubility Behavior – Solubility tests should be performed on every unknown. The solubility of an organic compound in water, dilute acid, or dilute base can provide useful information about the presence or absence of certain functional groups.

WebOrganic qualitative analysis involves four types of tests. 1. Measurement of physical properties includes determining refractive index, boiling points, melting points, and density. 2. Solubility tests can suggest the size and polarity of an unknown compound and the presence of basic or acidic functional groups. WebA pure liquid has a constant boiling point (at constant pressure). A change in boiling point during distillation is an indication of impurity. The opposite proposition, however, is not always true, and a constant boiling point does not necessarily mean that the liquid is pure. For instance, if two miscible fempower mlu
