Lab 3: Solubility of Organic Compounds Objectives: Understanding the relative solubility of organic compounds in various solvents. Exploration of the effect of polar groups on a nonpolar hydrocarbon skeleton. Introduction: The solubility of a solute (a dissolved substance) in a solvent (the dissolving medium) is the most important chemical principle underlying three major techniques you will study in the organic chemistry laboratory: crystallization‚ extraction‚ and chromatography.

Does Your Window Have Minor Damage? Tips For Repairing The Glass Your home’s windows should be able to take on their fair share of stress from the weather‚ but they can become damaged. It could be a chip from hail that impacted at high speeds‚ a fallen limb from a tree‚ or even your child throwing a toy towards the glass. Repairing minor damage is something that you can do on your own‚ and will help the windows remain strong. These tips will help you do it. Clear Resin A useful tool for repairing

Thus a solution α-naphthol 1a‚ 4-methylbenzaldehyde 2a and tert-butyl isocyanide 3a in EtOH was magnetically stirred at 45 C for 12 hours under an oxygen atmosphere with an equimolar ratio of the three reactants. TLC monitoring of the reaction mixture exhibited formation of a new product‚ which was purified (Table 1‚ entry 1). Identification of its structure by NMR spectroscopy revealed that it was 2-(4-methylbenzoyl)-1-naphthyl N-(tert-butyl)carbamate (4a). Next‚ in order to improve the yield of

A Diels-Alder Reaction History and Application: The 1950 Nobel prize in chemistry was awarded to Otto Paul Hermann Diels and Kurt Alder for their breakthrough work on the discovery and development of [4 + 2] cycloaddition reactions i. This set of reactions are enormously useful in the synthesis of six membered rings in a single stepii. These are used in many pharmaceutical applications. Tamiflu® is a drug which

reacted with dilute sodium hydroxide at 300°C and 3000 psi pressure. The following figure illustrates the Dow process. Air oxidation of cumene The air oxidation of cumene (isopropyl benzene) leads to the production of both phenol and acetone‚ as shown in the following figure. The mechanisms for the formation and degradation of cumene hydroperoxide require closer looks‚ which are provided following the figure. Cumene hydroperoxide formation. The formation of the hydroperoxide

These differences are perhaps most highlighted in the medical field where stereochemistry of a molecule can be the difference between having a medically active‚ effective drug and a toxic‚ potentially

a lab experiment done on the ideal gas law to determine differences in gas based upon their “R” constant difference to 0.082057. A total of seven gases were tested‚ which included‚ Ethanol‚ Hexane‚ Cyclohexane‚ Pentane‚ Ethyl Acetate‚ Butane and Acetone. These gases were each heated and then condensed to liquid gas to find specific values and determined Ethanol as the gas closest to ideal behavior in this experiment. Introduction: The Ideal Gas Law demonstrates the relationship of the properties

Gram staining From Wikipedia‚ the free encyclopedia A Gram stain of mixed Staphylococcus aureus (Staphylococcus aureus ATCC 25923‚ Gram-positive cocci‚ in purple) andEscherichia coli (Escherichia coli ATCC 11775‚ Gram-negative bacilli‚ in red)‚ the most common Gram stain reference bacteria Gram staining (or Gram’s method) is a method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative). The name comes from its inventor‚ Hans Christian Gram. Gram staining
