The Michael addition is a reaction named after Arthur Michael. Discovered in 1887‚ this is a carbon-carbon bond making reaction. The result of the Michael addition is a 1‚4 addition of a nucleophile to an alpha‚ beta-unsaturated carbonyl carbon compound. A 1‚4 addition is also commonly referred to as a conjugated addition. Another result of this reaction is a 1‚2 addition of a nucleophile. Some of the common attacking nucleophiles used in this reaction are enolates. Enolates‚ a negatively charged

Motivation Motivation is important to a business such as McDonalds because the better and harder the staff work‚ the more productive they are and more likely for the business to make a profit. There are different ways to motivate a workforce financially and non-financially. Financial motivation By giving out rewards‚ this motivates the employee to work harder so they can achieve them. The main motivational factor for any worker is money; there are different motivation methods depending on how

cream that is burned. The exact origin of this food is a mystery‚ but most people believe that it was first made in England. Also‚ Trinity College remade Creme brulee in a form that looks like today’s Creme brulee. This food has a custard cream at the bottom and a layer of caramelized sugar on the top. There is one chemical reaction that is involved in making Creme brulee‚ which is caramelization. Caramelization is a process of the sugar getting oxidized. This happens at different temperatures for

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi and the reaction rate

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward.
