How does an aminothioether respond to sodium fusion extract test?

Text Solution

Verified by Experts

If the organic compound contains both nitrogen and sulphur, sodium thiocyanate is formed. This gives blood red coloured ferric thiocyanate with ferric ions.
`Na+C+S+NrarrNaSCN, Fe^(3)+SCN^(-)rarr[Fe(SCN)]^(2)`
If sodium fusion is carried out with excess of sodium, the thiocyante decomposes to yield cyanide and sulphide. These ions give their usual thests.
`NaSCN + 2NA rarr Na_(2)S + NaCN`

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. In the process of testing elements in Lassaigne's a test, which of the following reactions do not occur.
