# Why is a staggered conformer more stable than an eclipsed conformer?

If we consider ethane as a reference molecule for our conformational analysis and check their Newman projection we can easily see the two extremes. The staggered conformation with the dihedral angle of ${60}^{o}$, where the H atoms on the 1st carbon are at maximum separation from H atoms on the 2nd carbon. In contrast stands the eclipsed conformation where the H atoms line up perfectly!
