Wittig reaction

According to the New World Encyclopedia, a calorimeter is an instrument used to measure the amount of heat absorbed or released by matter through a physical or chemical reaction. The world’s first ice calorimeter was used by Antoine Lavoisier and Pierre-Simon Laplace to determine the heat produced during various chemical reactions. Their experiments set the foundation for Thermochemistry. Improvements in technology create room for other types of calorimeters such as the brand calorimeter, isothermal

SN2 Reactions: Nucleophilic Substitution at Saturated Carbon Date of Experiment: February 6, 2008 Objective: The objective of this laboratory experiment is to study both SN1 and SN2 reactions. The first part of the lab focuses on synthesizing 1-bromobutane from 1-butanol by using an SN2 mechanism. The obtained product will then be analyzed using infrared spectroscopy and refractive index. The second part of the lab concentrates on how different factors influence the rate of SN1 reactions. The

Displacement Reactions Purpose: The purpose of the lab is to determine and observe the different double displacement reactions that occur when certain reactants are mixed. Double displacement reactions will be classified with the use of indicators. Introduction: Chemical reactions occur very often in people’s everyday lives. There are six main types of reaction. These include decomposition reactions, synthesis reactions, single-displacement reactions, double displacement reactions, combustion

Substitution Reaction Justiniano, Priscilla Raiza N. School of Chemical Engineering and Chemistry, Mapua Institute of Technology, Intramuros, Manila, Philippines Experiment No.1, Submitted on August 6, 2011 at N402. Abstract EXPERIMENT NUMBER ONE IS ALL ABOUT THE ELECTROPHILIC SUBSTITUTION OF AROMATIC COMPOUNDS. AROMATIC COMPOUNDS ARE THOSE ORGANIC COMPOUNDS WHICH HAVE BENZENE RING (CYCLOHEXA-1,3,5-TRIENE). AROMATIC COMPOUNDS ARE ALWAYS FOLLOWS THE SUBSTITUTION REACTION BECAUSE OF THE

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities, audition and vision, which were combined with two levels of warning signal status. The two levels of warning signal status were signal

What is hairspray made of? Hairspray is a solution of long, chainlike molecules (called polymers) in a very volatile solvent. Spraying deposits a stiff layer of the polymer on your hair after the solvent evaporates. The solvent used was once a compound of carbon, fluorine, and chlorine (a chlorofluorocarbon, or CFC). CFCs are nontoxic, nonflammable, and make almost ideal aerosol propellants. But when it was learned that they causedestruction of stratospheric ozone, they were replaced with other

chemical reaction with another chemical. (Dickinson et al. 180) The higher the element is on the Activity Series the more reactive it is. (Dickinson et al. 192) A reactive element will replace an element that is underneath it in the activity series. (Dickinson et al. 192) In this lab we will examine chemical reactions with the activity series, indicators and the type of chemical reaction it is. The purpose of this lab is to study chemical change and analyze why and how chemical reactions are created

This Chapter discusses the progress made using the Nottingham Pulse Rig towards determining the mechanism of the Fischer Tropsch reaction. A summary of the three main mechanisms proposed in the literature was outlined in Chapter 1 but is still the subject of much debate.1-6 Generally the carbide mechanism is accepted for Fe catalysts,7 but the mechanism over Co catalysts is less clear.1 Ge and Neurock,8 as well as Ojeda et al.,4 have suggested that the carbide mechanism is the pathway for FT synthesis

images of each other that are non-superimposable. In an achiral enviroment, they do not rotate plane-polarized light with the same ability, but they exhibit the same physical and chemical properties. In a chiral enviroment, enantiomers show different reactions with other molecules. The configuration of the enantiomer is what determines the direction that it will rotate light. Light will either be rotated to the left or to the right. Most enantiomers produced in a lab have a value of zero as their net rotation

Abstract: The Effects of Temperature on Catechol Oxidase. Lania Ellis, 2014, 102 Student Center Dr. San Marcos, TX 78666. Temperature can affect the reaction of catechol oxidase by speeding up or slowing down the reaction. I was able to see what happened to the absorbance after changing the temperature of the catechol oxidase solution. I did this by heating and cooling the solutions to measure the absorbances in hot, cold, warm, and room temperature. Then the data was compared to see how the temperature
