Rebecca Hardy Section 4 Ashleigh Stapleton June 18‚ 2012 Experiment 32: Identification of a Conjugated Diene from Eucalyptus oil Introduction In this experiment‚ the purpose was to prepare the Diels-Alder adduct of the unknown conjugated diene in Eucalyptus oil and determine the approximate percentage of diene in Eucalyptus oil. To discover the product of this reaction‚ isolate the adduct‚ and classify the diene from the melting point of its adduct. The unknown was one of four conjugated dienes

Exponential growth in petrol and diesel fueled vehicles are responsible for deterioration of air quality in cities. Because of the increase in urbanization‚ industrialization and commercial activities in the urban areas‚ the demand for transport has also been increased. In addition to it the use of personal vehicles has also increase steadily. The various principle pollutants emit from vehicles are as follows- Carbon monoxide (CO) Suspended particulate matter (SPM) Oxides of nitrogen

(Clark 2007) A polar solvent‚ such as mixtures of water and methanol or acetonitrile is also used. Non-polar compound in the solution is attracted to the hydrocarbon group due to van der Waals dispersion forces. On the other hand‚ the attraction between the polar solvent and polar molecules in the mixture being passed

Testing for functional groups The chemistry for carbon is vast; there are in excess of ten million known carbon compounds. It is estimated that 300000 new carbon compounds are discovered each year. Organic molecules contain functional groups that are responsible for their chemical properties. Functional groups will react with certain regents in predictable ways‚ making it possible to develop diagnostic reactions to test for their presence in an organic molecule. Common functional groups found

As a chemical‚ sugar is poison for the body and the cause behind numerous ailments. We’re addicted to its taste and find it impossible to avoid… but as we will see later in this article‚ safe and healthy alternatives are becoming available. As we pass through the supermarket aisles perpetuating another generation of dental decay‚ obesity‚ weakened bones‚ diabetes‚ hyperactivity‚ emotional imbalance and dysfunctional immune systems‚ we must ask ourselves the compelling question of why

determine the identity of the functional group. The first test‚ the 2‚4-dinitrophenylhydrazone test‚ determines the presence of a carbon-oxygen double bond. Brady’s reagent‚ another name for the test‚ is a solution of 2‚4-dinitrophenylhydrazine‚ methanol‚ and sulfuric acid. When performing the test‚ a bright orange or yellow precipitate shows the presence of an aldehyde or ketone. This test proceeds via a nucleophilic addition-elimination reaction‚ as shown below.1 The Tollen’s test is used to distinguish
