General and Organic Chemistry Laboratory Experiments for Science , Pre-medical, and Pharmacy studentsChapter IV: Identification and Purification of Organic CompoundsBy Khalid M Darwish
Abstract: In order to identify an organic compound, a chemist needs to apply the suitable technique, depending on the compound state. Accordingly, melting point identification is applied for solids, boiling point for liquids, and sublimation for some compounds which have the tendency to sublime. On the other hand, When an organic compound is isolated from its natural source such as plants, it can be contaminated with some other undesirable compounds, called …
