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

In Isomer B only one υ(CO) mode was observed with frequency of 1880 cm-1‚ hence Isomer can considered as a cis-isomer and isomer B a trans-isomer. Results Isomer A Isomer B Isomer A was obtained as a very fine‚ light yellow‚ crystalline powder. Mass of Isomer A Produced: 1.155 g Mass of [Mo(CO)6] Used: 0.5020 g n = m/Mr = 0.5020 g /264.00 g/mol

A primary brain injury is the damage to the brain at the moment of impact (Tran‚ 2014). This damage to the brain initiates oedema‚ inflammation and ischemia which if not controlled could lead to a secondary brain injury (Tran‚ 2014). If these factors are not controlled they may worsen the secondary brain injury by further disrupting cerebral blood flow (CBF)‚ supply of oxygen and glucose to support

Energy is stored in the body mostly in the form of fat‚ which is needed in the diet to supply essential fatty acids‚ substances required for growth but not produced by the human body. Dietary fat is needed to carry the fat-soluble vitamins A‚ D‚ E‚ and K and to aid in their absorption from the intestine. Fats are a group of chemical compounds that contain fatty acids. There are three main types of fatty acids: saturated‚ monounsaturated and polyunsaturated. A saturated fatty acid has the maximum
