Vedclass · Answer

(D) The Hofmann mustard oil reaction is a characteristic test for primary amines $(R-NH_2)$.In this reaction,a primary amine reacts with carbon disulfide $(CS_2)$ followed by heating with mercuric chloride $(HgCl_2)$ to form an alkyl isothiocyanate,which has a characteristic mustard-like smell.Secondary amines $(R_2NH)$ and tertiary amines $(R_3N)$ do not contain the necessary hydrogen atoms on the nitrogen to form the isothiocyanate intermediate.Among the given options,$N-$Methyl$-1-$propanamine is a secondary amine $(CH_3CH_2CH_2NHCH_3)$,therefore it does not give the Hofmann mustard oil reaction.
