Hyperconjugative and Stereoelectronic Effect

College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, P. R. China

In recent years, hyperconjugation is considered as the main reason why ethane prefers cross conformation. In this article, we review the history of hyperconjugation theory, a significant part of stereoelectronic effect. Furthermore, we explore the relationship between conformation analysis, reactivity and hyperconjugation, demonstrate the significance in probing molecular structure, and also make a discussion about the hyperconjugation explanation for the preference of ethanein cross conformation.
