Hydrazine Formula – Equation and Problem Solved with Example

Hydrazine has the inorganic base and taken as the important reagent for the preparation of a plenty of nitrogen compounds. The chemical formula for this substance is NH2NH2 with a molecular weight of 32.04 g/mol approx. The chemical structure of the compound is also given below where two amine groups NH2 are connected together by covalent bonds in a pyramid shape.

Hydrazine Formula

The natural occurrence of hydrazine can be seen in microorganisms like yeast, bacteria, or fungi etc. This is an intermediate anaerobic oxidation for ammonia. The chemical can be prepared by Raschig process where sodium hypochlorite solution is combined with excess ammonia with the help of an intermediate and prepared hydrazine as the final product.

NaOCl + NH3 → H2N-NH2 + HCl

The product can also be prepared by adding urea instead of excess ammonia.

H2N-CO-NH2 + NaOCl + 2 NaOH → N2H4 + H2O + NaCl + Na2CO3

The product has a strong odor and it is a denser colorless liquid with a density of 1.02 g/mL and a boiling point of 114 °C. The product is highly flammable and it can be dissolved in water quickly.

Further, the product is pretty reactive and can be defined as the reducing agent too which is widely used for the organic synthesis process. This is moderate but gets highly alkaline with aqueous solutions. The product reacts violently with metal or its oxides that may results in hazardous explosions later. It is highly toxic too at high concentrations and cause irritation to eyes, nose, throat etc.
