    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

    Relative Reactivity of Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions‚ and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution‚ or unimolecular displacement. In the first step of the mechanism

    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

    Conversion of Alcohols to Alkyl Halides Ankita Patel August 6‚ 2013 Introduction This lab consisted of the conversion of alcohols into alkyl halides through common substitution methods. These methods include SN1 and SN2 mechanism‚ both of which can occur for this type of reaction. For both reactions‚ the first step of protonation will be to add hydrogen to the –OH group and then the rest of the reaction will proceed according to the type of mechanism. SN1 reactions form a cation intermediate

    Substitution Reactions of Alkyl Halides Purpose: To examine the relative rates of various alkyl halides under Sn1 and Sn2 conditions. We will be examining Sn2 reactions with the Finkelstein reaction. The conditions for this are NaI in acetone. NaI is soluble in acetone but the products of the reaction; NaCl and NaBr are not. We will watch the reaction by looking for the first appearance of the solid salts. Acetone is a good solvent for Sn2 reactions because it is a polar aprotic solvent
