Consider the reaction, $R \mathrm{CHO}+\mathrm{NH}_2 \mathrm{NH}_2 \longrightarrow \mathrm{RCH}=\mathrm{N}-\mathrm{NH}_2$ What sort of reaction is it?
  1. Electrophilic addition elimination reaction
  2. Free radical addition elimination reaction
  3. Electrophilic substitution elimination reaction
  4. Nucleophilic addition elimination reaction

Solution

In this reaction acts as nucleophilic species which adds on carbon. Therefore this is the case of nucleophilic addition reaction. Simultaneously, a mole of $\mathrm{H}_2 \mathrm{O}$ also eliminated. Therefore, overall this reaction is a nucleophilic addition elimination reaction.
