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

Anthony Young Partner: Nick Dale TA: Alekhya 6/15/15 The SN2 Reaction: Factors Affecting SN2 Reaction. Introduction In the substitution reactions‚ the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons‚ present on the nucleophile is used to create a new bond with the carbon atom‚ from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon
