STEPS IN SCIENTIFIC RESEARCH: ARCHITECTURAL RESEARCH: AN INTERDISCIPLINARY REALITY Hypothesis is a tentative explanation that accounts for a set of facts and can be tested by further investigation. Generation of Research Hypothesis Research usually starts with a problem. Questions‚ objectives and Hypotheses provide a specific restatement and clarification of the problem statement/research question. In qualitative research‚ the research question may assume two forms: The grand tour

group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction completed‚ affording the target product in high yield (70%). The structure of RH-PY was analyzed by 1H-NMR and ESI-TOF. Figure S1 shows the 1H-NMR spectrum of RH-PY. Interestingly‚ there are two series of peaks (a‚ a′ and b‚ b′)‚ characteristics

3-perylenepentanol‚ M4 39‚ 51 To a solution of 3-perylenepent-4-ynol‚ M3 (0.32 g‚ 0.957 mmol) in THF (20 mL)‚ Pd/C (600 mg‚ 3 wt% on activated carbon) was added. Nitrogen gas was turned off‚ hydrogen gas balloons were used to supply H2 gas to the flask. The reaction mixture was stirred for 15 h under hydrogen atmosphere at room temperature. Ethyl acetate was added to the reaction mixture and the Pd/C was removed by filtration. Solvent was removed in vacuo to afford 3-perylenepentanol as yellow solid

Compilation of “Dehydration of Methylcyclohexanol” Blog entries: A common Sophomore Organic Chemistry laboratory experiment that has great potential for further research is the acid catalyzed dehydration of simple alcohols. The classic dehydration of 2-methylcyclohexanol experiment that was introduced in Journal of Chemical Education in 1967 Taber(1967)JCE:44‚p620. The rather simple procedure of distilling an alcohol with an aqueous acid has spawned several investigations that have resulted

Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

Consulting Chemists Institute Introduction The Consulting Chemists Institute was contracted by a local food manufacturer to determine if sodium benzoate‚ a common food preservative‚ undergoes significant chemical changes at the pH level encountered in the acidic environment of the stomach. Experimental Method Sodium benzoate was prepared by addition of an equimolar amount of aqueous sodium hydroxide (3 M‚ ~ 20 ml) to a benzoic acid (1.256 g‚ 10.3 mmol) /water mixture (10 ml). Benzoic
