Pure Biphenyl freezes at 71.0 c. A solution of 1.44 g of Anthracene (C14 H10 molar mass = 178.2 g/mol) and 12.87 g of biphenyl froze at 21.1 c. Calculate Kf of Biphenyl. The solution has 1.44 g of anthracene in 12.87 g of solvent also have 1.44 g/ 178.2 g / mole of the solute = 0.00808 moles in 12.89 g of solvent moles of solute / kg of solvent = 0.008008 x 1000 / 12.89 = 0.62690

INTRODUCTION The purpose of this experiment is to synthesize trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig

of Daphnia is predators‚ algal resources‚ and temperature. 6. It is relevant to understand Daphnia biology because UVR should be considered side by side with predators‚ algal resources and temperature when looking at diel vertical migration. Also‚ wider ranges of lakes such as droughts‚ acidification‚ and modification in land use can change optical characteristics of DOC and therefore increase UVR penetration.
