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 the 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 ...Download file to see next pagesRead More

Hydrolysis of Phenyl Benzoate, Preparation of Cyclohexanol from Cyclohexene and Diels-Alder reaction of Maleic anhydride with Cy
When the crude product is acidified and re-basified to give out phenol, a base-catalytic reaction is involved. This reaction is often referred to as the acid-catalytic reaction (Borths, 2006). As widely cited, the hydrolysis of esters could be catalysed either through a base or through an acid.
