Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic acid as our acid catalyst which would be protonating the hydroxyl group of our butanol‚ to make a better leaving group‚ so that the bromine radical would be able to attack the leftover carbocation. Our group used 2-bromobutanol and we expected‚ from our mechanism‚ to achieve 2-bromobutane and when we compared our GC results to the prepared sample‚ our mechanism proved to be true. We did

INORGANIC CHEMISTRY 1 Lab Report on Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more

SYNT 0719 – Brominating Alkenes OBJECTIVE The purpose of this lab will be to brominate trans-stilbene by using acetic acid and pyrimidium tribromide by refluxing the mixture. To test the purity of product I will take the melting point which should be around 240 ºC along with a flame test which should be green-blue. CHEMICAL PROPERTIES TABLE See Attached Lab Notebook Copies REACTION MECHANISM In this lab we used multiple techniques to complete and verify the bromination of trans-stilbene

molecules hold them together. The larger the molecule (as it moves down the halogen group) the bigger the intermolecular forces are between electrons because with more rings the distance between each electron is larger. The larger elements such as Bromine and Iodine are larger molecules with a larger amount of intermolecular force between each electron. This increase in intermolecular attraction means that the required heat energy to reach the boiling point increases. Fluorine has a significantly lower
