In addition‚ there could be moisture present in the solid leading to errors in the weight. Based on the NMR spectral data‚ the frequency of the signals was 15.6Hz‚ which is very close to the theoretical frequency of 12-18Hz. This confirms that the compound is

Thus‚ it is ideally suited to the students. The NMR and IR spectra of the compound 2 may he used to illustrate the geminal and vicinal couplings along with the effect of the dihedral angle on the latter (Fig. 2) and the coupled vibrations of the

Introduction: For this lab‚ the main focused involved alkanes and hydrocarbons. Essentially‚ the free-radical chain of chlorination of 1-Chlorobutne. Free radical-chains occur because alkanes are chemically unreactive with most agents. However‚ the free-radical chain allows a pathway of certain functional groups like alkyl chloride or bromides. In addition‚ chlorine atoms can possibly be made from molecular chlorine under low to mild conditions with the usage of a catalytic amount of an initiator

The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

Introduction: This experiment focuses on carrying out a Perkin Reaction to synthesize (E) and (Z) isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acid‚ acetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table

Introduction Tetraphenylporphyrin will be synthesized and metallated with silver acetate. After purification and NMR and UV-visible spectra was taking for the original porphyrin synthesized and the silver porphyrin. From this data obtained we will talk about silver’s effect on porphyrin. Theory Porphyrin is important to study because it plays keys roles in biological process; they are responsible for giving plants and blood their colors green and red respectively. Porphyrins have the iron chelate
