The hetero elements in organic compound are nitrogen, halogen, sulphur

1.	The hetero elements in organic compound are nitrogen, halogen, sulphur and phosphorousd, Nitrogen is estimated by Duma's method (or) Kjeldahl's method. The other hetero elements are estimated using Carius method.In the estimation of halogen by Carius method, which of the following is carried out
Answer» Oxidation of compound by CONC, `H_(2)SO_(4)` HEATING of the compound with fuming nitric acid and `AgNO_(3)` Combustion of the compound Dissolving of compound directly into aq. `AgNO_(3)` SOLUTION :In carius method, the halogen is precipitated as silver halide by heating the compound with fuming `HNO_(3)` and `AgNO_(3)`
