What the elements of an organic compound?
An organic compound is one in which one or more carbon atoms are linked to hydrogen, oxygen or nitrogen atoms. Sometimes an organic compound will contain phosphorus or sulfur but organic compounds with these elements are rare.
Why only sodium is used in Lassaigne's test?
because of its electropositive nature. it is cheap also. although potassium can be used but it is costly... and lithium is less electropositive... Lassaigne's test is a test for the detection of halogens, nitrogen and sulphur in an organic compound. These elements are covalently bonded to the organic compounds. In order to detect them, these have to be converted into their ionic forms. This is done by fusing the organic compound with sodium metal. The ionic compounds formed during the fusion are extracted in aqueous solution and can be detected by simple chemical tests. The extract is called sodium fusion extract or Lassaigne's extract.
Why you make sodium extract?
This a part of experiment to check the different element in an organic compound ,the element which has to be detected is covalently linked with carbon to convert the covalent bond into ionic bond sodium is heated with organic compound.
The two elements found in every organic compound are?
Carbon and hydrogen. For this reason, CO and CO2 are not considered organic compound, whereas CH4 is.Carbon and Oxygen I think..
What elements combine to produce carbon in an organic compound?
No elements combine to produce carbon. Carbon is an element in and of itself.
Why is it necessary to prepare sodium extract for the detection of foreign elements?
We need to prepare sodium extract for the detection of foreign elements because foreign elements are found in organic compound bonded covalently. As a result they cannot be detected through organic compound directly. Hence they are first converted into ionic compound with the help of sodium extract
What are foreign elements in an organic compound?
Organic compounds may contain other elements than carbon, hydrogen and oxygen such as nitrogen ,halogen, sulphur, etc....these elements are known as foreign element.
What elements does organic compound have?

What 2 elements make a compound organic?
carbon and nitrogen
What is the function of the sodium chloride in the procedure in salting-out effect?
sodium chloride helps to decrease the solubility of an organic compound therefore its easier to extract an organic compound almost completely from water
