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.

Key words: Hyperconjugation, Ethane conformation
