Isomerism - Stereoisomerism - Geometrical and Optical Isomerism

In Lassaigne’s test, an organic compound containing nitrogen and chlorine gives a Prussian blue color but no silver hali

Prussian blue indicates nitrogen (forming NaCN), but no AgCl precipitate suggests chlorine is not ionic or not extracted as NaCl, possibly due to covalent bonding not broken by sodium fusion.
