摘要:

针对亲核试剂亲核性和碱性的关系,从“结构决定性质”的原则出发解释了二者的一致性,结合软硬酸碱理论和空间因素解释了二者的不一致性。

关键词: 亲核试剂, 亲核性, 碱性

Abstract:

This paper provides a practical explanation of the comparison between nucleophilicity and basicity of nucleophiles. The similarities are explained based on the principle of "structure determines property", and the differences are explained by combining Hard-Soft-Acid-Base theory and the steric hindrance factor.

Key words: Nucleophile, Nucleophilicity, Basicity
