Essay On Benzophenone

6. The solubility of the solids were tested using a micro tray, by placing them in water and oil to observe their polarity,

Benzophenone was soluble in methyl alcohol whiles biphenyl was partially soluble. Benzophenone and biphenyl are both nonpolar molecules. Methanol is intermediately polar, allowing both nonpolar molecules to be dissolved as it is not too polar or nonpolar. However, biphenyl is less polar than benzophenone. Since methyl alcohol is somewhat polar, the more polar benzophenone is more soluble in methyl alcohol than biphenyl. Also, benzophenone can make hydrogen bonds. Thus, benzophenone is more soluble in methyl alcohol than

The following equations and calculations are necessary in order to assess the results of the experiment. Calculation 1 utilizes Eq.1 to determine the mass and actual yield of triphenylmethanol on a watch glass. In all of the following calculations, “LR” refers to benzophenone, the limiting reagent of the experiment, and “Product” refers to triphenylmethanol.

Substance A and B were weighed; Substance A weighed 0.502 g and substance B weighed 0.503 g. Both substances were put into two different test tube with approximately 8 ml of DI water into the test tub. Substance A and B were stirred and B dissolved while A did not. This shows that B is soluble in water compared to A. Thus, shows that B is soluble in water than A. The reason why B is soluble in water is because it has a higher dipole moment than A. With a higher dipole moment, it shows that it is soluble in water since it is polar and the bonds were easily broken.

2) Explain your result of miscibility / immiscibility for water and diethyl ether. Make use of the concepts of polarity and of the

“Meth, not even once” is a popular phrase that is associated with this drug. This drug has many known horrible effects associated with it, plus many effects more I am sure are going to be discovered over time. I am intending to cover the history, effects, the different categories of meth abuse, and the withdrawal effects of Methamphetamine in this paper, and what to do if you suspect someone you know is using meth.

“Meth is a very strong drug that attacks the central nervous system stimulant.” “The drug works directly on the brain and spinal cord by interfering with normal neurotransmission (“HOW METH DESTROYS.” 1) Meth is also potent an easy to make only thing you need is a few boxes of cold and asthma medications containing ephedrine or pseudoephedrine, red phosphorous, hydrochloric acid, drain cleaner, battery acid, lye, lantern fuel, and antifreeze are among the ingredients most commonly used. Longtime meth abuse causes brain damage, various oral cancers and oral infections, as well as psychotic behavior, and various skin conditions; it also decreases nerve sensitivity.

Americans have been using drugs like morphine, heroin, and cocaine and marijuana. When the 20th century began, the United States began to take notice to its first drug epidemic. The government gradually instituted effective restrictions, by passing laws that limit the distribution of opium and coca crops. During the 1960s, drugs like amphetamines, and psychedelics came on the scene, and a new generation embraced the use of these drugs. With the drug culture expanding, our government developed new laws and agencies to target the problem. In 1973, through executive order President Richard Nixon founded The U.S. Drug Enforcement Administration (DEA) to enforce federal drug laws. In the 1980s, crack appeared causing the addiction rate to sky rocket

After the initial mixture has refluxed, 9.11 grams of benzophenone was dissolved in 100 mL of anhydrous ether in a beaker and was then transferred into the separatory on the reflux apparatus. This solution was then added to the Grignard reagent at a drop wise rate while stirring. After the benzophenone was added, the mixture was then refluxed for 15 minutes on a heating mantle.

Systemic lupus erythematosus (SLE) is an autoimmune disease that manifests in the form of undesirable inflammation. SLE is a disease that is beginning to be more and more common, and as such, its detection and treatment is a developing field of rheumatology. The disease can pose many threats in various ways, including, but not limited to, adverse hematologic, neuropsychiatric and musculoskeletal effects that may present in the form of low bloods counts, high levels of anxiety, and joint and muscle pain respectively. Studies have shown that antimalarial drugs such as plaquenil (generic name: hydroxychloroquine) may function as immunosuppressants, and due to this plaquenil is often used as a preliminary treatment for mild cases. Hydroxychloroquine is primarily used to treat the musculoskeletal effects of SLE, but also has unforeseen benefits such as increased bone density and cholesterol level maintenance (Jordan and D’Cruz, 2016).

The strong demand and high prices on world markets of rubber and China's promotion of overseas investment through its opium replacement policy. These economic factors have converged with the desperate need of impoverished highlanders in northern Laos to opium replacement to a cash crop as a consequence (Alton, 2005) the Northern uplands is rapid change and expansion of smallholder rubber. While rubber provides an attractive investment opportunity for local and foreign investors, the Lao government envisages it as one of the options in stabilizing shifting cultivation, reduce opium production and generating income for upland farmers. However, with a relatively small area having been planted with rubber and an even smaller area in production,

3F-Phenmetrazine is also referred to as 2-(3-fluorophenyl)-3-methylmorpholine and 3-fluorophenmetrazine is actually the analogue of Phenmetrazine, which is basically a compound consisting of a Phenethylamine backbone.

Dow Chemical Company and Shell Oil Company manufacture a substance known as Dibromochloropropane (DBCP). There have been many adverse effects due to exposure to DBCP, including but not limited to infertility. Due to these adverse effects that are often caused by inhalation exposure, the Environmental protection agency (EPA) banned DBCP in the United Stated. Dow and Shell shipped gallons of DCBP to Costa Rice to be used by Standard Fruit. Many employees of Standard Fruit that were exposed to the chemical, became infertile and sued Dow and Shell.

As mentioned in the discussion, olive oil, vegetable oil, crisco, and lard were soluble in nonpolar solvents and insoluble in polar solvents. This is due to the chemical composition of polar and nonpolar substances which results from the molecular shape as well as properties of dissolving solutes in solution. Polar substances are hydrophilic and contain polar Van Der Waals interactions (intermolecular forces) such as dipole-dipole forces, ion-dipole forces, and hydrogen bonding. Nonpolar substances are hydrophobic and contain non-polar Van Der Waals interactions. ‘Like dissolve like’ is the reason only polar solutes dissolve in polar solvents and why nonpolar solutes dissolve in nonpolar solvents. Molecules with similar polarity have similar intermolecular forces and therefore, can interact with each, or in this case dissolve9. Additionally, the solubility of a compound is determined by the length of the hydrocarbon chain. Long hydrocarbon chains such as the one found in oleic acid makes a compound more insoluble10. Therefore, since the lipids used in this experiment were hydrophobic substances and each lipid has long hydrocarbon chains, the results were consistent with the scientific literature and principles.

Organic compounds are, by definition, any chemical compound containing carbon. These compounds include carbohydrates, polysaccharides, lipids, proteins, and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the fats of a cell. Proteins are the building blocks of muscle in a cell. Nucleic acids are used to transfer genetic information from one cell to the other.
