between the pure tert-butyl chloride and not. In this experiment‚ tert-butyl chloride is synthesized from tert-butyl alcohol. Introduction Alkyl Halides (also known as halogenoalkanes or haloalkanes) are a group of chemical compounds derived from alkanes containing one or more halogens. They are a subset of the general class of halocarbons‚ although the distinction is not often made. Alkyl Halides are widely used commercially and‚ consequently‚ are known under many chemical and commercial names. A

Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

herbicides are an example of dangerous synthetic chemicals used around the world. Chemical pesticides are synthetic chemicals used to kill and prevent pests from impeding agriculture. For example‚ toxaphene is a synthetic organic insecticide made by the chlorination of camphene‚ a toxic fuel known for almost being insoluble in water (http://www.epa.gov). Toxaphene contains over 670 chemicals and does not occur naturally (http://www.aadnc-aandc.gc.ca). Improper irrigation or bad weather can cause pesticide

Although vaccination has proved to be an effective measure in preventing disease‚ controversies remain over whether the risks of side effects of vaccinations outweigh the risk of contracting the disease. Vaccination is the process when pathogenic cells are injected into the cells of a healthy person so that the body develops immunity through antibodies to that virus or bacterium. The U.S Center for Disease Control and Prevention recommends that children get 16 vaccines including Diphtheria‚ hepatitis

INTRODUCTION The word "anesthesia"‚ coined by Oliver Wendell Holmes‚ Sr. (1809–1894) in 1846 from the Greek αν-‚ an-‚ "without"; and aisthēsis‚ "sensation")‚ refers to the inhibition of sensation. An anesthetic (American English) (or anaesthetic‚ (Commonwealth English)) is a drug that causes anesthesia—reversible loss of sensation. They contrast with analgesics (painkillers)‚ which relieve pain without eliminating sensation. These drugs are generally administered to facilitate surgery. A wide

many purposes‚ including the separation of compartments containing aqueous solutions from each other‚ that’s where lipids come in. The water-insolubility of lipids is due to the fact that the polar groups they contain are much smaller than their alkane-like (nonpolar) portions. These nonpolar portions provide the water-repellent‚ or hydrophobic‚ property (1). An important use for lipids‚ especially in animals‚ is
