Purification and Characterization of organic compound worksheet
Purification and Characterization of organic compound worksheet Most of the organic substances when synthetically prepared or isolated from natural source are impure due to the presence of some bye-products or reactants. Before the compound can be analysed qualitatively or quantitatively, it is necessary that it should be in a pure state. Purification is not always easy and various methods depending upon the nature of the compound and impurities are employed. Here, you can find some questions related to “Purification and characterization of...

Molecular mass determination worksheet The molecular mass (m) of a substance is the mass of one molecule of that substance, in unified atomic mass unit(s) u (equal to 1/12 the mass of one atom of the isotope carbon-12). This is numerically equivalent to the relative molecular mass (Mr) of a molecule, frequently referred to by the term molecular weight, which is the ratio of the mass of that molecule to 1/12 of the mass of carbon-12 and is a dimensionless number. Thus, it is incorrect to express relative molecular mass (molecular weight) in...

Detection of elements Worksheet It is a general 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. Here, you can find...
