reduction‚ or in the addition of a functional group. In this lab we will examine the stereoselectivity of the reduction of 4-tert-butylcyclohexanone (Figure 1) using sodium borohydride (Figure 2). In the first week of this lab we will use sodium hypochlorite (Figure 3) to oxidize (Mechanism: Figure 6) commercial 4-tert-butylcyclohexanol‚ synthesizing 4-tert-butylcyclohexanone and using IR analysis to confirm that our oxidation was successful. In the second week of this lab we will use sodium borohydride

Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to determine those ratios. During this reaction‚ hypochlorite ions oxidize the thiosulfate ions according to the unbalanced and incomplete reaction

Fluorine Properties - What are the Physical Properties of Fluorine? What are the Physical Properties of Fluorine? The Physical properties of Fluorine are the characteristics that can be observed withoutchanging the substance into another substance. Physical properties are usually those that can be observed using our senses such as color‚ luster‚ freezing point‚ boiling point‚ melting point‚ density‚ hardness and odor. The Physical Properties of Fluorine are as follows: What are the Physical

drops of sodium hypochlorite necessary to make a diluted food dye change to colorless in less than three minutes helps calculate the absorbance which can then be analyzed to find the pseudo rate constant and eventually leading to the rate constant and the rate law. The results show that the m and n are both 1st order which makes the overall order of the blue dye 2nd order. Results: In this experiment‚ rate laws and graphs help calculate the oxidation of food dyes by sodium hypochlorite. During the

Titration Analysis of a Commercial Bleach A. Purpose ! ! ! To review oxidation-reduction reactions and their stoichiometry. To learn the concept and technique of redox titration. To determine the percent (m/v) of an active ingredient‚ sodium hypochlorite (NaOCl)‚ in a commercial bleaching agent. B. Theoretical Background Whereas acid-base reactions involve the transfer of a proton‚ oxidation-reduction or redox reactions involve the transfer of electrons from one substance to another‚ resulting
