Diels-Alder Reaction Lab Report Example | Topics and Well Written Essays - 500 words

Diels-Alder Reaction - Lab Report Example Characterization of the products is through chemical tests discussed in Mayo pages 266. The experiment cyclopentadiene and maleic anhydride were reacted with the aqueous solution to form an n organic compound in crystal form. The composition of the cyclopentadiene does make it possible for such a reaction to proceed; it has 5 carbon rings that contain 2 carbon- carbon double bonds, which are separated by single alpha bonds. Purification of the crystalline product is typically accomplished by pipetting the solution from the underlying crystal products and consequently drying it. Diels-Alder reaction entails the preparation of the six-membered carbocyclic rings, which are conjugated diene with an alkene. The reaction of the product takes place in the single step to produce carbon-carbon bonds with the four stereocenters. The product is the adequate for the direct characterization. The reaction entails two reactants that are the butadiene and maleic anhydride, which both results to the functional groups to the corresponding product. In addition, the infrared spectrum of t he segregated material depicts the observation. The spectrum of the 3-sulfolene is representative on an alkene sulfone. Thus, the underlying macro group train for an unconjugated five-membered ring alkenes fits the underlying data rationally. The non-polar ought to exhibit a more solubility in petroleum ether in place of the hexane. It is mainly due to stronger van-der-Waals forces in the ether. Due to the presence of larger alkanes in petroleum ether, more intermolecular forces exist than hexane. For this reason, the presence of petroleum ether; the solubility is high for polar molecules yet with the increase in solubility denotes the decreased yield, hence less product. The presence of the two stereocenters coupled with the long range rotating is linked via the pie system of the alkene. The whole H spectrum is

Microeconomics Assignment Example | Topics and Well Written Essays - 500 words - 1

Microeconomics - Assignment Example However with the reduction of trade barriers in the American market during the 1980’s, the luxury automobile market saw increased competition from European and Japanese automobile makers. In terms of a supply and demand analysis, it is likely that there would be increased variety in the market of luxury automobiles and an overall increase in the supply of vehicles. It stands to reason that there must be a reduction the in price of American luxury automobiles to help increase quantity demanded to meet the new market equilibrium or improvements must be made to reduce the costs of manufacturing vehicles so that company profits can remain the same with a lower unit volume sale. The same kind of situation has occurred in Europe, with an over-supply of vehicles. In Europe, the market appears to be flooded with automobiles now. The supply is high. In order to compete in this crowded market, companies will have to reduce their prices. Demand simply does not match the supply, therefore prices must be lowered. Europe has almost 300 car and engine plants, according to the European Automobile Manufacturers’ Association (known as ACEA). Their collective capacity is thought to be about 27 million vehicles a year. Sales of new cars last year were just under 16 million and are expected to fall to as low as 14.5 million this year, according to Ford. The capacity was established when demand was high, before the recession. Because car manufacturing is so capital intensive it is harder than other industries to be flexible to economic downturns. Manufacturers are therefore more vulnerable. They will make cars based on information from a year earlier and scale up their factories to do so, when it turns out demand is not as high as they thought it was because people are scaling back their spending on things like cars, they will produce an over-supply. They will then
