Ethane,hydrazine,and hydrogen peroxide are three structurally similar substances composed of the elements from the same period with hydrogen,respectively.However,their stability significantly decreases in a sequential manner,and their stable conformations are also dissimilar.These differences have not been explained adequately in the current textbooks.This article provides a possible explanation for the variation in stability among these substances by analyzing their n-σ* hyperconjugation.Additionally,it elucidates the absence of anti-conformation in hydrazine and hydrogen peroxide.The hyperconjugation theory is extended to illustrate and to discuss stability and stable conformation of inorganic compounds.
