Esmeralda Curiel Organic Chemistry October 21‚ 2014 Experiment 41- 1‚4-Diphenyl-1‚3-Butadiene INTRODUCTION The study of the Wittig Reaction is important because it is often used to form alkenes from carbonyl compounds. The purpose of this experiment is to isolate the trans‚ trans-1‚4-diphenyl-1‚3-butadiene‚ which is formed by a Wittig reaction along with the cis‚ trans isomeric diene. The reaction is carried out in two steps. First the Wittig salt is obtained through a simple nucleophilic displacement

Salt of the Earth Flannery O ’Connor ’s novels and stories are inhabited with unique and flawed characters who are the result of O’Connor ’s satiric worldly perspective. While they are sometimes humorous‚ these misfits are usually unpleasant. Critics have termed them "grotesque‚" but O ’Connor has rejected this term because it suggests that the characters are too weird to belong in the real world. Instead‚ O ’Connor insists that the South is inhabited by many such people. For every good or evil

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for themselves by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal

Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

effects of rock salt‚ which is used for melting snow in the winter time‚ works in a variety of ways. The main reason is to aid in melting of the snow making it easier for individuals to drive their vehicles and also the sidewalk for pedestrians. Overall‚ the rock salt used for melting snow‚ works but it have some pros and cons about it‚ but using it wisely should be the key to its success. Might grass growth be inhibited by salt? Introduction The usage of salt‚ (rock salt) is best used

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

opinions on the issue of the “Tar sands” or “Oil sands” (I shall use both unambiguously) development. Environmentalists (like myself) and concerned citizens in Canada‚ as well as the international community‚ decry that the largest industrial energy project on the face of the planet is destroying future generation’s right to clean soil‚ water‚ air‚ biodiversity and most importantly a stable climate. As well as strong local economy‚ the current economic setup of the tar sands’ development is to focus on

Bile contains water‚ cholesterol‚ fat‚ bile salts‚ proteins and a waste product call bilirubin. If the bile has too much cholesterol ‚ bile salt‚ or bilirubin‚ they hardens into stones. There are two types of Gallstones. The first and more common type is known as the Cholesterol Stone‚ which accounts for 80 percent of all cases of Gallstones

and I have been asked by the head office to write a report about the South Port Sand Dune system. Part 1: Kennedia Prostrata: Kennedia Prostrata is commonly known as the ‘Running Postman’. The Running Postman can spread up to 1.5 metres‚ followed but cylindrical pods that are 3cm-5cm in length. The Kennedia Prostrata has a light green leaf that contain 3 rounded leaflets. The species are naturally adapted to sand or light soil. That means that it is easy to maintain and can planted where it needs
