Subsequently‚ mixture of synthesized benzopinacol‚ glacial acetic acid and iodine crystal reacted in an acid-catalyzed rearrangement wherein dehydration of benzopinacol resulted into the formation of carbocation. In this state‚ an aromatic shifted and then‚ forming delocalized carbocation. Afterward‚ regenerating the catalyst stabilized the molecule into benzopinacolone. After qualitative and quantitative analysis of the products‚ it was found out that benzopinacol was successfully

COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid. The

In our daily diets‚ carbohydrates‚ fats‚ proteins and water are the main components in our food. However‚ if the food is left untreated‚ oxidative deterioration of the flavor and odor of fats and fatty constituents in it will be resulted. Hence‚ antioxidant are used widely in the production of food which fats and oils are used as raw materials and in the marketing of foods containing fats under modern conditions. The major factor in quality degradation of fats and fatty portions of foods is oxidation

CO2 + 4H2 O (Naphthalene) Combustion Introduction of the Product: Naphthalene is an organic compound with formula C10H8. It is the simplest polycyclic aromatic hydrocarbon‚ and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon‚ naphthalene’s structure consists of a fused pair of benzene rings. It is best known as the main ingredient of traditional mothballs. Explanation: It’s formed

Bladder cancer‚ like most cancers does not develop as a result of a single pathogen or behavior. Rather‚ there is a complex interaction between genetics‚ environment‚ and lifestyle which can result in an increased risk for developing cancer of the bladder. The most common risk factor associated with bladder cancer is smoking. A Meta analytical study of several case studies in Europe found that cigarette smokers were about 3.3 times more likely to develop bladder cancer than nonsmokers. (Tide‚ 2015)
