November 15, 2007 synthesis of 1-bromobutane introduction: the purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide in order for this reaction to reach completion there are four major operations that need to be performed.
= the 1-bromobutane was formed by the addition of bromine or hydrogen bromide to 1-butene, then the bicarbonate neutralizes any unreacted bromide this. 2-bromobutane is an isomer of 1-bromobutane both compounds share the molecular formula c 4 h 9 br 2-bromobutane is also known as sec -butyl bromide or methylethylbromomethane because it contains bromine , a halogen, it is part of a larger class of compounds known as alkyl halides. Determine which layer is the 1-bromobutane layer, you take a test tube and add 5 ml of water to it, then remove a few drops of the bottom layer from the separatory funnel and see if they fall through the water to the bottom.
