In ethane, the most stable conformation is the staggered form, where the hydrogen atoms on adjacent carbons are positioned as far apart as possible, minimizing electron repulsion. In butane, the conformational analysis is more complex due to the presence of larger substituents. The anti conformation, where the two methyl groups are positioned 180° apart, is the most stable form of butane. The gauche conformation, where the methyl groups are closer (60° apart), is less stable due to steric hindrance. These conformational preferences impact the stability and reactivity of both ethane and butane, with staggered and anti conformations being the most energetically favorable\n
