Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting

Introduction When you think about love what do you think about? We as humans often think of “love” basically as the core of understanding romance‚ but that is not the whole entire thing‚ well the most accurate picture. So what is love? The answer to the question is that some people may seek a philosophical and/or spiritual answer. Love is not a material or a design. It is basically a word that we use to sugar coat over various‚ complex‚ and also chaotic‚ realities of our human relationship. Instead

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

Honor and slavery‚ written by Kenneth Greenberg‚ dives into the substance of a system well known by white men of the Old South. Many so called ¨rules¨ can be used to describe the practice of honor of which these men mastered. Examples of men of honor are sporadically mentioned in an attempt to enhance the understanding of the alleged language. Greenberg’s arguments can easily be challenged by other historical events. Specifically‚ Protestant Christianity‚ including the Second great awakening‚ brought

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. A typical example is as followed and is considered a molecular equation

The Reaction to the Alchemist In life‚ it is hard to come across a good book. Millions of books are published each year‚ all over the world. J.D. Salinger‚ the author of the Catcher In The Rye says‚ “What really knocks me out is a book that‚ when you’re all done reading it‚ you wish the author that wrote it was a terrific friend of yours and you could call him up on the phone whenever you felt like it. That doesn’t happen much‚ though.” That statement is in fact true. When you come across a good
