Objective The objective of this experiment is to understand the Sn2 reaction by synthesizing 1-
bromobutane from n-butanol.
The first step of this experiment was to mix 2.0mL of n-butanol and 4.0mL of 48%
hydrobromic acid in a 10mL round bottom flask. It was then placed in a beaker of ice. Black
boiling stones and 2.0mL of concentrated sulfuric acid was then added. The mixture was then
refluxed for 45 mins. After cooling, the top layer of n-bromobutane was removed. To the
bottom layer, 2mL of 3M sodium hydroxide was added. The bottom layer was removed and
dried. In two test tubes, .2mL of butanol and .2mL of the product were added. To each tube, .
5mL of sodium iodide was added and the results were recorded.
