Vedclass · Answer

(C) The oxidation of primary amines like ethylamine $(CH_3CH_2NH_2)$ with $KMnO_4$ proceeds through the formation of an imine intermediate. $1$. Ethylamine is oxidized to acetaldimine $(CH_3CH=NH)$. $2$. The imine intermediate undergoes hydrolysis to form acetaldehyde $(CH_3CHO)$,which is an aldehyde. Reaction: $CH_3-CH_2-NH_2$ $\xrightarrow{[O], KMnO_4} CH_3-CH=NH$ $\xrightarrow{H_2O} CH_3-CHO + NH_3$.
