उत्तर
Propanal will undergo an addition elimination reaction with hydrazine to give corresponding hydrazone derivative containing C = N bond (imine).
\[\begin{array}{cc}
\phantom{}\ce{H}\phantom{....................................}\ce{H}\phantom{.......}\\
\phantom{}|\phantom{.....................................}|\phantom{........}\\
\ce{\underset{\text{Propanal}}{H3CH2C - C = O} + \underset{\text{Hydrazine}}{H2N - NH2}->\underset{\text{Hydrazone derivative}}{H3CH2C - C = N - NH2} + H2O}
\end{array}\]
