Ethyl amine undergoes oxidation in the presence of KMnO4KMnO_{4} to form

A

An acid

B

An alcohol

C

An aldehyde

D

A nitrogen oxide

Answer

An aldehyde

Explanation

Solution

CH3−CH2−NH2Ethylamine→KMnO4[O]CH3−CH=NHAldimine\underset{\text{Ethylamine}}{CH_{3} - CH_{2} - NH_{2}}\underset{\lbrack O\rbrack}{\overset{\quad KMnO_{4}\quad}{\rightarrow}}\underset{\text{Aldimine}}{CH_{3} - CH = NH}

→H3O+CH3−CHOAcetaldehyde\overset{\quad H_{3}O^{+}\quad}{\rightarrow}\underset{\text{Acetaldehyde}}{CH_{3} - CHO}
