Vedclass · Answer

(D) The mustard oil reaction is a characteristic test for primary amines $(R-NH_2)$ with $CS_2$ and $HgCl_2$,so statement $A$ is correct.$1^o$ amines are basic and react with chloroplatinic acid $(H_2PtCl_6)$ to form insoluble salts of the type $(RNH_3)_2PtCl_6$,so statement $B$ is correct.$1^o$ amines contain active hydrogen atoms attached to nitrogen,which react with sodium metal to release hydrogen gas $(H_2)$,so statement $C$ is correct.$1^o$ amines do not undergo hydrolysis to form alcohols; instead,they react with nitrous acid $(HNO_2)$ to form diazonium salts (which are unstable and decompose to alcohols) or other products depending on the structure,but the direct hydrolysis of an amine to an alcohol is not a standard reaction. Thus,statement $D$ is incorrect.
