Abstract:The Wittig Reaction is a nucleophilic addition in which an alkene is formed as a product. Both the E and Z isomers of the alkene result. Substituents on the aromatic aldehyde affect the E/Z ratio of products that form. In this experiment‚ a nitro group was used as the substituent in the ortho‚ meta and para positions‚ with benzaldehyde as the control. Each of the four aldehydes reacted with (carbethoxymethylene) triphenylphosphorane to produce ethyl cinnamate‚ ethyl-3-(2-nitrophenyl)acrylate

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

Physics Behind The Theory of special relativity And Related Concepts RESEARCH PAPER Abstract: Prior to albert Einstein’s theory of special relativity there was always an idea about relativity. Through Galilean transformations‚ which worked perfectly with the newton’s laws of motion‚ people had formed a vague idea that all motion in this world

Chemistry Exam Study Sheet Organic Chemistry • Study of compounds to which carbon is the principal element. • Carbon is special because it has 4 bonds. Functional Groups • Organic substances are organized into organic families. • Organic Families – group of organic compounds with common structural features. o Each family has a recognizable physical property and a specific structural arrangement. o Each combination is referred to as a functional group. o Even

The missing part O α + β could be transformed into another compound or then the ES-product diol to be converted in turn into ES-ether‚ ES-hydroxy-ether or other product. This could be verified by a UHPLC analysis coupled with mass spectroscopy (UHPLC-MS). It would be interesting to determine the SE of the adsorption kinetics of α + β and ES-diol by performing sorption isotherms on ferrihydrite

E. Review of Related Literature Chemical Repellents It is no wonder that‚ considering all of the above mentioned diseases‚ humans have worked for decades searching for a way to repel these insects. In 1946‚ a chemical called DEET (N‚ N-diethyl-m-toluamide) was developed by the US Army and released for civilian use in 1957. DEET confuses the receptors of most biting insects‚ rendering them virtually ‘blind’ and thus much
