Abstract

A kinetic investigation has been carried out to determine the rate of replacement of bromide from 1-bromo-1-nitroethane by the iodide of potassium iodide in an acetone medium, and to study the effect of the nitro group on this bromine replacement. The chemical reaction was started by adding a measured amount of potassium iodide in acetone, to a measured amount of 1-bromo-1-nitroethane in acetone which was in a ground glass-stoppered Erlenmeyer flask. The flask was then immersed in the constant temperature water-bath. The reaction was stopped after a specified time, with addition of excess crushed ice to the reaction mixture. The concentrations of the iodide and bromide ions were determined by a poteniometric method, using a Fisher Titrimeter equipped with a silver electrode and a saturated KCI-calomel reference electrode. From the kinetic data obtained, the rate constants have been calculated, at various temperatures and concentrations of the reactants. These kinetic data were interpreted in the light of the known chemical literature, and the mechanism of the reaction is proposed.
