REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand‚ the

There are five different types of cement in the dental field each is versatile in their properties‚ uses‚ and mixing techniques. Many were traditionally used for routine cementation through the nineteen ninety’s and since have been replaced by newer makeup and mixing techniques. The selection of cement for a specific procedure requires knowledge of the chemical and physical properties of each particular cement for the specific restorative process to be performed. This first cement I’m going to discuss

fractional distillation. Once the fraction has been collected it must then be dried. The dried distillate is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double bond present. To assure the results were correct the chemical tests were done. The Bromine test was found

acetaminophen‚ aspirin‚ or ibuprofen. Then we used the Infrared Spectroscopy to determine the function group of the molecules to help us identify which analgesic was used. Between the symptoms‚ melting point‚ and results of the infrared spectroscopy we were able to identify what analgesic Jasper ingested. Results: After receiving all of the information and comparing the results of the symptoms‚ melting point‚ and infrared spectroscopy we concluded that they analgesic he was given was ibuprofen

Title: - Infrared Spectroscopy‚ Boiling point and Melting point. Introduction: - Infrared spectroscopy has also made a break though in medicine. It used to evaluate the kidney stone diseases thus broadening the use of IR in different ways. The purpose of this lab experiment is to identify the unknown solutions using the Infrared Spectroscopy (IR)‚ boiling point‚ and melting point (1). The IR helps to determine the compounds such as a functional group. In order to analyze the compound‚ IR and melting

bottom and thus allowing it to be separated. The total amount of 1-bromobutane formed was 2.065 grams. In order to confirm that the reaction occurred correctly and that 1-bromobutane was formed‚ infrared spectroscopy as well as halide tests were performed on the product. Infrared spectroscopy works on the basis that different covalent bonds of molecules can stretch and bend. These bonds can undergo vibrations which require energy that corresponds directly with the energy absorbed from infrared
