The gas-phase basicity strength order of six alkylamines, namely methylamine, dimethylamine, trimethylamine, ethylamine, diethylamine, and triethylamine, was compared using computational chemistry methods. The calculated free energy changes indicate that the overall basicity order is triethylamine>diethylamine>trimethylamine>dimethylamine>ethylamine>methylamine. In addition, the hybridization types of orbitals occupied by lone pair electrons of the six bases show that the N atom in methylamine, dimethylamine, trimethylamine, ethylamine, diethylamine, and triethylamine exhibits sp^4.16, sp^5.09, sp^6.08, sp^4.07, sp^4.83 and sp^6.53 hybridizations, respectively, suggesting that the basicity orders are trimethylamine>dimethylamine>methylamine; triethylamine>diethylamine>ethylamine. Integrating computational chemistry into the teaching of organic chemistry has not only deepens students’ understanding of the acid-base theories, but also broadens their perspective on hybrid orbital theory, thereby this method is worthy of widespread promotion and application in chemistry teaching.

The Hartree-Fock-Roothaan(HFR)equation is the core of Molecular Orbital Theory(MOT),but the interdisciplinary nature of this equation usually renders its principle difficult to be understood by both postgraduate and graduate students.In this work we take the computational chemistry experiment of the single-point energy calculation of H₂O molecule as an example,by analyzing the computational process and understanding the output files of Gaussian 16 program so that students can gain an intuitive and perceptual understanding the solution of HFR equation.This approach helps to open the black box of the solution process of HFR equation and lays a solid foundation for subsequent learning of high-level molecular orbital theory and density functional theory.
