摘　　要：锂与带有孤对电子的电负性较大的原子或基团接近时(也可扩展到电负性较弱的基团),产生类似于氢键的静电相互作用称为锂键。本文综合锂键发展历史和最新进展探讨锂键和氢键的异同点,为大学化学氢键知识的学习提供知识远迁的新素材。在加深对氢键概念理解的同时,增强学生关注科学前沿的意识,进而实现扩展学生视野,培养创新能力的教学目标。When lithium is close to the electronegative atom or group with lone pair electrons(which can also be extended to the less electronegative group),the electrostatic interaction is called lithium bond,which is similar to hydrogen bond.In this paper,the development and the latest progress of lithium bond are reviewed,and meanwhile the similarities and differences between lithium bond and hydrogen bond are discussed,so as to expand the knowledge of hydrogen bond in general chemistry teaching.We aim to deepen the students’understanding of hydrogen bonding concept as well as enhance students’awareness of scientific frontier,students’vision and innovative ability.
