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.

Key words: Hydrogen bond, Lithium bond, College chemistry, Reform of education
