Date: 9th February‚ 2011 Title: Analysis of the Elements present in Organic Compounds Aims: To test the presence of Carbon‚ Hydrogen‚ Oxygen‚ Nitrogen and Sulfur in Organic Compounds Introduction: Organic Compounds can be considered as any compound containing carbon atoms covalently bonded with other atoms‚ usually hydrogen. Other atoms may include oxygen‚ nitrogen‚ sulfur…etc. They can be found in nature‚ since “organic” means present in‚ or derived from‚ plants and animals. Materials/
