Question

Why is hydrazine a good nucleophile than ammonia ??

Answer 1

Answer:

Explanation:

Despite that NH2NH2 (Kb~10^-6) is a weaker protic base by comparing with NH3 (Kb~10^-5), the nuclrophilicity of NH2NH2 is generally considered stronger than that of NH3. One of the rationales for this discrepancy is due to an alpha-effect of NH2 group in hydrazine, while no such effect in NH3.
