Benzil Reduction Introduction The objective of the experiment was to reduce Benzil‚ using sodium borohyride as the reducing agent. In a benzil reduction‚ there are five possible products than can occur‚ specifically a racemic mixture of benzoin‚ racemic mixture of hydrobenzoin‚ or meso-hydrobenzoin. Therefore‚ three different tests were conducted in determining the identity of the product: melting point‚ thin light chromatography‚ and infrared spectroscopy. (a) Mechanism and reaction equation

Case 13 Reducing Fertility in Bangladesh Geographic area: Bangladesh Health condition: in the mid-970s‚ a Bangladeshi woman had more than six children on average. in combination with poor nutrition and lack of access to quality health services‚ this high fertility rate jeopardized the health of both the woman and her children. Beyond the health impact‚ high fertility and rapid population growth represented a major constraint to the country’s economic development and social progress. Global importance

“Kinetics of Ethanol Oxidation” laboratory experiment utilized Beer’s law and spectroscopy to monitor concentration and the rate of ethanol oxidation through the LoggerPro System. This data then helped determine the kinetic rate constant‚ k‚ and the order of the reaction. First‚ the wavelength of maximum absorbance was determined using the LoggerPro interface and a Vernier colorimeter. Beer’s law was then used to determine the molar absorptivity. Finally‚ a kinetic study of ethanol oxidation was completed

Acidity’s effects on Fruit Browning Aim: To test whether the acidity of the surface area of an apple has an effect on the rate of enzymatic browning over 70 minutes. Hypothesis: the more acidic the surface area the longer it takes for the fruit to oxidise. Variables: Independent: acidity of surface area of the apple Dependent: the progression of melanin (brown pigment) after 70 minutes Controlled/fixed: time of day‚ knife used to cut fruit‚ portion of fruit‚ environment

uncertainty reduction theory from its origin to date. Ever since uncertainty reduction theory was first created‚ many researchers have examined it by comparing it with other theories. Uncertainty reduction theory had been tested across different cultures in order to confirm its generalizability. It had also been applied to real life situations to examine how individuals interact in their initial encounters with strangers. In addition‚ researchers suggested testing uncertainty reduction theory beyond
