Experiment 1: Preparation of 1-Bromobutane and Reactivity of Alkyl Halides Objective: The purpose of this lab is to prepare 1-bromobutane from 1-butanol in an acid-catalyzed substitution reaction. While the reaction would be expected to occur as SN2 due to the primary nature of the substrate‚ because H2SO4 is used as a solvent‚ the conditions are very polar and the reaction can proceed via an SN1 reaction. The main objective is to obtain test results to determine the mechanism of the reaction

Objective To compare the relative reactivities of different alkyl halides with two different reagents; sodium iodide in acetone and silver nitrate in ethanol. Below the reaction equations 1. RX+NAIRI+NAX (X=Cl or Br) in the presence of acetone 2. RX+AgNO3+EtOHROEt+AgX+HNO3 We used three substrates primary secondary and tertiary compounds are 1-bromobutane‚ 2-bromobutane and 2-bromo-2-methylpropane respectively to react with the two nucleophiles that are sodium iodide with acetone solvent and

Welcome to the blue collar city of Buffalo‚ New York. I find myself in my great Uncle Wills old brick home in the center of South Buffalo. The house has the familiar smell of old people‚ in the foyer are a pair of work boots the leather old and worn‚ the soles nearly depleted. A layer of dust has formed on the boots that have remained untouched for decades. As I move closer to the kitchen I can hear the recognizable sound of stainless steel clinking on ceramic‚ the rhythmic noise can only be one

Psychiatry and Clinical Neurosciences‚ 64: 403–407. Basis for the research question in past research and theory: Hypogeusia‚ the reduced ability to taste‚ and dysgeusia‚ the distortion of the sense of taste‚ mainly involving the sour‚ bitter and salty tastes‚ have already been demonstrated in anorexia nervosa patients in literature

Rejection of Relative Claims and Acceptance of Objectivism Curtlers reasons for rejecting ethical relativism and subjectivism are many. However‚ before I discuss these reasons it is important to note that there are several forms of arguments. One being cultural relativism that makes statements based on an individuals culture. Another form that is closely related to relativism is subjectivism. Subjectivists make statements based on their individual beliefs as well as accounting for context. Subjectivists

Testing the Reactivity of Metals Aim: To prove the arrangements of the metals (Na‚ Ca‚ Mg‚ Al‚ Zn‚ Fe‚ Sn‚ Pb‚ Cu) according to the reactivity series. Background Information: By using various experiment‚ the reactivity of the metals can be deduced by the observation of the reaction. Hypothesis: Metals with low ionisation energy will lose their their electron more easily providing a more vicious and obvious result‚ as compared to the metals with higher ionisation energy‚ as the metals with lower

Virtue ethics is relative There are different opinions and views within virtue ethics as to which virtues to follow and‚ more importantly‚ what makes a "Virtuous person" the contrast in opinions demonstrates the relativism of Virtue ethics. The doctrine of the mean does not work in practice It seems perfect in theory but as the statement claims‚ it is difficult to work in practise. The main area of failure is when/ how we know when we’ve gone to either extreme? This judgement amongst subjective

Brief History of Relative Deprivation The “Relative Deprivation Theory” dates back nearly 65 years ago. Samuel Stouffer invented the notion of relative deprivation.(Pettigrew ‚ walker kitabı) Samuel Stouffer made a survey with American soldier in World War II. Survey’s results was improbable. According to the survey’s results military police more pleased than U.S. Army Air corpsman even though military police’s promotions were slower than U.S. Army Air corpsman’s promotions. Stouffer indicated that

Relative pronouns can be used quite differently in Spanish than in English‚ and the fine points of their use goes well beyond what would be expected of beginners. So keep in mind that most of this lesson focuses on the most common usages; as you learn Spanish you will learn other sentence constructions as well. Relative pronouns are pronouns that are used to introduce a clause that provides more information about a noun. Thus in the phrase "the man who is singing‚" the relative pronoun is "who";
