Question

Why staggered conformation is more stable than eclipsed?

Answer 1

Answer:

Staggered conformations are more stable than eclipsed conformations because the C-H bonds are farther apart via a C-H bond bisecting an H-C-H bond on the adjacent C (60 degrees). Eclipsed conformation aligns the C-H bonds, forcing the atoms too close together and thus creating steric strain and torsional strain.
