Abstract Hydrogen bonding is widespread in nature and is the foundation of the unique properties of substances such as water and ice.This paper focuses on comprehensive reform in the teaching of hydrogen bonding by integrating knowledge systems from structural chemistry and physical chemistry.It systematically introduces the characteristics of hydrogen bonds in water and ice,and,starting from the reconstruction of microscopic hydrogen-bond networks,provides an in-depth analysis of the water-ice phase transition process and its thermodynamic stability as depicted in phase diagrams.The paper emphasizes the differences between the stable states shown in phase diagrams and the actual kinetic pathways of phase transitions.By integrating content from both structural and physical chemistry and incorporating molecular dynamics simulations into the teaching process,it visually demonstrates the full evolution of molecular arrangement from disorder to order during the freezing of water.The paper also highlights recent achievements by Chinese scientists in the study of water and ice,particularly breakthroughs in scanning probe microscopy techniques.Through multidimensional instructional design,the approach aims to enhance students’ thinking skills,research capabilities,and creativity,thereby achieving effective integration of structural and physical chemistry.
