It is a simple condensation reaction which proceeds with elimination of water. Aldehyde RCHO reacts with hydrazine NH 2 NH 2 to form hydrazone RCH = NNH 2. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/b1134c6740b5fb1051ae2b21093b52b0-.png" />
