Unlike water, hydrazine is very reactive and is sometimes used as a fuel for small rockets. One hydrazine reaction producing gaseous products is represented by the balanced equation below. N2H4 (1) → N2 (g) + 2H2 (g) + heat A. The electronegativity value of nitrogen is 3.0 and that of hydrogen is 2.1. Based on the electronegativity difference, identify the type of bond in hydrazine, N2H4. B. Explain in terms of polarity, why hydrazine, N,H4, is very soluble in water. C. Explain, in terms of intermolecular forces, why the boiling point of hydrazine is so high at standard pressure. D. Compare the atomic radius of nitrogen, N, and hydrogen, H2.…
