the product is a solid‚ you should give a melting point and compare it to the known melting point and then give a percent error. You should also comment on the physical appearance of the product. You should include information obtained from IR‚ GC or NMR. (refer to example in syllabus) d) Next you should draw a conclusion based on your data. You should never say the unknown was….

EFFECTIVENESS OF BASIL ( Ocimum Basilicum Lamiaceace ) PLANT FOR URINARY TRACT INFECTION INTRODUCTION Background of the Study The care of Urinary Tract Infection (UTI) is a common costly problem in acute care and home care population. Many therapies have been made for the treatment. Despite this‚ the patient still suffer from pains when urinating and the financial burden. In the locality‚ Urinary Tract Infection was commonly experienced among teenagers due to lifestyle and diet. Nurses in the community

Nitration of Acetanilide Introduction When organic compounds are nitrated it changes the composition and reaction of the compounds.[4] We could benefit from these changes‚ nitration of acetanilide produces a product called p- Nirtoanoline. P-Nitroaniline is commonly used as an intermediate in the synthesis of dyes‚ antioxidants‚ pharmaceuticals and gasoline. P-Nitroaniline is also used in gum inhibitors‚ poultry medicines and as a corrosion inhibitor. [2] Nitration is a type of chemical

Although investigating a new pathway to form a compound is challenging and time-consuming‚ the reward of observing correct NMR peaks is phenomenal and ecstatic. For instance‚ I was trying to add few functional groups on tropone. This should be relatively simple‚ and the procedure indicated that I should be able to make this compound with high yield and purity. However‚ TLC and NMR indicated that my product had a significant amount of impurity. I

Abstract In this experiment‚ 4-(4-chlorophenyl)-3‚4-dihydropyrimidine-2-one is synthesized in a solvent-free reaction‚ where urea‚ ethyl acetoacetate‚ 4-chlorobenzaldehyde are used as the reactants and p-toluenesulfonic acid is used as the catalyst. This reaction is similar to the original synthesis of DHPM by Pietro Bignelli‚ as it incorporates a single step. Due to its environmentally friendly conditions‚ such as the use of solar energy as a heat source and the lack of solvent‚ this synthesis of

Sucrose is a disaccharide formed from D-glucose and D-fructose. The glycosidic linkage is between C1 of glucose and the C2 of fructose. 1H NMR of Sucrose: Mass Spectrum of Sucrose: 13C NMR spectra of sucrose: 3. Why is it difficult to isolate sugars? For simple sugars‚ they are small molecules and they behave similar properties that make them hard to separate. Besides‚ sugars are most electrically neutral. The separation of electrically neutral sugars is a relatively difficult and
