The qualitative analysis of an organic compound involves the detection of all the elements present in it. Elements which can be present are: Carbon, hydrogen, sulphur, nitrogen, halogens, phosphorus, oxygen etc. Carbon and hydrogen are generally present in almost all the organic compounds.
1. For detection of carbon and hydrogen, we use copper oxide test.
2. For detection of nitrogen, soda lime test or lassaigne's test are used.
3. For detection of sulphur, sodium nitroprusside test or lead acetate test can be used.
4. For detection of halogens, beilstein's test or lassaigne's test can be used.
The quantitative analysis of an organic compound involves the determination of the percentages of the variuos elements present in a given compound.
1. Estimation of Carbon and Hydrogen is done by Liebig's method.
2. Estimation of Nitrogen is done by Duma's method or Kjeldahl's method.
3. Estiamtion of halogens is done by carius method.
