ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound. One example of a compound being can be synthesized in the laboratory is acetylsalicylic acid‚ commonly known as aspirin. It is variedly used for different

Formation of Hydrocarbons Types of hydrocarbons Parameters for hydrocarbon accumulation Phases of alteration of organic matter Types of kerogen Migration of hydrocarbons Five Major Types of Hydrocarbons Kerogen: Kerogen is a fine-grained‚ amorphous organic matter. It is not soluble to normal petroleum solvents‚ like carbon disulfide. Its chemical composition is 75% C‚ 10% H‚ 15% other (sulfur‚ oxygen‚ nitrogen‚ etc.). It is very important in the formation of hydrocarbons because it is what generates

"The Answer is No" Historical content is not necessary for the reader to understand the short story "the Answer is No" by Naguib Mahfouz. It is possible to understand the theme of the story without knowing the author’s background or the story’s historical context. "The Answer is No" is about a fourteen year old girl who gets sexually assaulted by her new tutor who is of the same age as her father. The tutor tries to convince her to marry him in exchange for her education at a prestigious College

We underwent two different reaction schemes using Dipotassium phosphate (K2HPO4) and Potassium hydroxide (KOH) to isolate the compounds of pure Acetylsalicylic Acid/Aspirin and N-(4-hydroxyphenyl) Ethanimidate/Acetaminophen respectively from Excedrin. The first reaction scheme to undergo acid-base organic extraction was to isolate the most acidic compound in Excedrin with a weak base‚ K2HPO4. We isolated the aspirin using aqueous base extraction‚ with Dipotassium phosphate then treated with HCl

1. Summary of Experiment In this experiment we will be comparing the both SN1 and SN2 reactions using various compounds and sodium iodide and silver nitrate. We will be comparing the nature of the leaving group (Cl vs Br) in the 1-halobutanes as well as the effect of the structure of the compound. The effect of the solvent polarity and temperature will also be looked at. Name Structure M.W. M.P. B.P. Density Toxicity Sodium Iodide NaI 149

The Answer Is No From centuries to centuries the role of women has been predominantly subordinate to the role of men. Men have been known to be superior in both physical and mental levels. They are also most likely to have an "upper hand" in situations based on their gender. An example of such situation is taken place in "The Answer Is No"‚ written by Naguib Mahfouz. This story has a considerable amount of sexual politics. On one side you have a women who is powerless and feels trapped because of
