    a seperatory funnel and about 10 mL of water was added. The funnel was shook gently while venting. The layers were then separated and the organic layer was observed. The organic layer was then washed with 2 M of aqueous NaOH solution and then with about 10 mL of saturated NaCl solution. The cloudy 1-bromobutane layer was then transferred to a 25-mL Erlenmeyer flask and dried over anhydrous. The flask was swirled occasionally for 10-15 minutes until the crude 1-bromobutane is clear. The crude

  • Essay on Discussion and Conclusion: Preparation of 1-Bromobutane

    spectroscopy of 1-bromobutane should have a large carbon-hydrogen peak which absorbs at approximately 3000 cm-1 and a medium carbon-bromine peak which absorbs at 500 cm-1. However, due to the limitations of the infrared spectroscopy machine, a carbon-bromine peak should not be detected because the machine is not accurate at infrared ranges below 600 cm-1. As a result, relying simply on a carbon-hydrogen peak is not a reliable way to determine if the product is actually 1-bromobutane. This is where
