CH241 – Lecture Outline Chapter 6: Reactions of Alkenes Carbocations How are carbocations classified? What stabilizes a carbocation and why? What is the Hammond Postulate? How does the stability of the carbocation intermediate effect the number of products and why? What are the three types of carbocation rearrangements and why do they occur? Stereochemistry of Reactions (read 6.14 in 7th edition before class) What are the three ways a reaction can have stereochemistry? (a) What is

Introduction The transportation in this case study is a chicken transportation from chicken farm to egg farm. There are 4 types of truck which are ten-wheel truck‚ eight-wheel truck‚ modified four-wheel truck and ordinary four-wheel truck. Each type of truck has different capacity moreover each hen’s farm has different in quantity supplied as same as each egg’s farm also have

and chemical properties in terms ofstructure and behaviour. Nitration test (test for the presence of aromatic ring)‚ Bromine test (test for the presence of unsaturation)‚ and Basic oxidation test (test for an alkyl substituted benzine) were done. We were given an unknown which we tested (Nitration‚Bromine‚ Basic oxidation) and found out that it was an aromatic unsaturated hydro carbon. Keywords: hydrocarbons‚ hexane/ cyclohexane‚ cyclohexene‚ naphthalene‚ toluene 1. Introduction

Compared to other samples‚ sample 4 had the highest absorbance readings. There wasn’t any enzymes in the blank sample because there wasn’t any enzyme samples in that tube. Hence‚ the oxidation process did not occur and the products weren’t formed‚ not resulting in significant change of absorbance reading. On the other hand‚ all other sample showed enzyme activity through decreased in their absorbance. Samples 2 and 3 had the greatest

Americans consume too many calories‚ often in the form of added sugars and fats‚ but too few vitamins and minerals‚ in part because the intake of fruits‚ vegetables‚ and milk products is relatively low. (Insel & Roth. 2008 p.367) There are many ways that American’s can incorporate fitness and nutrition in their daily lives. This paper will discuss fitness and nutrition habits‚ and suggest new habits that will benefit your health and promote healthy weight. a)

Sarah Johnson Personal Response to Survival in Auschwitz “Why is the pain of every day translated so constantly into our dreams‚ in the ever-repeated scene of the unlistened-to story” (Levi‚ p 60)? As I read this quote in my book‚ I highlighted it and wrote in the margin “foreshadowing”. I feel confident that these dreams signified just that; that the author (amongst the other survivors) would forever re-live those horrors and try tell their stories…and no one listens. The poem at the beginning

organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions • Oxidations – loss of electrons • Dehydrogenations – lost electrons are accompanied by protons – A hydrogen atom is lost (1 electron‚ 1 proton) Redox • During redox reactions‚ electrons carry energy from one molecule to another • Nicotinamide adenosine

ABSTRACT African Renaissance is synonymous to Afrocentism and Pan-Africanism‚they all share a common goal. All these terminologies have being a common currency in African for some time now. Though promoted by past leaders‚ but it became pronounced and made popular by Thabo Mbeki. This paper gives the root meaning of the concept of African Renaissance as it also exposes the ills caused by colonialism. This paper goes further to expose diverse heroes who stood for the freedom of the African continent
