Vedclass · Answer

(C) The formation of Prussian blue colour in the Lassaigne's test (sodium fusion test) indicates the presence of both nitrogen and carbon in the organic compound,which react to form sodium cyanide $(NaCN)$.$Na + C + N \rightarrow NaCN$This $NaCN$ then reacts with ferrous sulphate $(FeSO_4)$ to form sodium ferrocyanide,which further reacts with ferric ions to produce ferric ferrocyanide,known as Prussian blue.Among the given options,only $CH_3-CH=NH$ contains both carbon and nitrogen atoms.Therefore,it will give a positive test for nitrogen.

Sodium fusion extract of which compound gives Prussian blue colour with $FeSO_4$?
