Acidified sodium fusion extract on addition of ferric chloride solution gives blood red colouration,which confirms the presence of:

The presence of halogen in an organic compound is detected by:

During the fusion of an organic compound with sodium metal,the nitrogen present in the organic compound is converted into:

Which compound is responsible for the formation of a blue precipitate when ferric ions react with a Lassaigne's extract or potassium ferrocyanide solution?

When sodium fusion extract of an organic compound is boiled with iron$(II)$ sulphate solution followed by addition of concentrated $H_2SO_4$,it gives a Prussian blue colour. This confirms the presence of which element?

Consider the following table$-$

Column-$I$	Column-$II$
$A$. Best and latest technique for isolation,purification and separation of organic compounds	$i$. Chromatography
$B$. In Lassaigne's test for $N$	$ii$. Vacuum distillation
$C$. In Lassaigne's test for $S$	$iii$. Violet coloured complex is formed
$D$. Aniline is separated from water by	$iv$. Prussian blue coloured complex is formed
$E$. Glycerol is purified from spent lye	$v$. Steam distillation

The correct match is$-$
