INTRODUCTION TO ASCLEPIAS CALIFORNICA The terrestrial plant‚ Asclepias californica‚ is the primary food source for Monarch butterflies. It can only germinate and produce seeds if provided with the proper environmental influence. The California milkweed’s population is spread out in the southern and coastal areas of California where there are flat lands and grassy slopes. It can also grow up to three feet tall and have clumps consisting of multiple stems that are a couple of feet in width. Unlike

Preparation and SN1 Reactivity of 2-Bromobutane Paul DeJong Department of Chemistry‚ Illinois State University‚ Normal‚ IL 61790-4160 Submitted: April 4‚ 2013 Introduction The purpose of part 1 of the lab is to prepare 2-Bromobutane using SN1 reactions. The purpose of part 2 of the lab is to determine the relative reactivity of alkyl halides under SN1 conditions. Results and Discussion The Overall Reaction The Proposed Mechanism Experimental Procedure To prepare

In this experiment‚ the objective is to successfully perform an SN1 reaction to determine the reactivity of tert-butyl chloride‚ through the usage of sodium iodide/silver nitrate reagents and to synthesize tert-butyl chloride. The tert-butyl chloride was synthesized through the use of separation (aqueous and organic layers) and distillation. Tert-butyl chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane

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

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

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

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

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

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
