Nitrogen, sulphur and halogens are tested from the sodium fusion extract of the organic compound which is commonly known as Lassaigne's extract. For preparing Lassaigen's extract, a small quanty of the organic compound is fused with sodium metal in a fusion tube. The red tube is broken in distilled water, boiled and filtered. This filtrate is known as Lassaigne's extract or sdodium fusion extract.Which of the following is not applicable to Lassaigne's test

Answer» The nitrogen, halogens and sulphur are converted into inorganic salts It can be used for the DETECTION of hydrogen in the organic compound During fusion of the organic compound with Sodium, `Na_(2)S, NaCN` and NaX are FORMED It is possible to DIFFERENTIATE between halogens Solution :Lassaigne.s is not applicable for the detection of C & H.
