Staggered and eclipsed conformers In the staggered conformation, the
H atoms are as far apart as possible. This reduces repulsive forces
between them. This is why staggered conformers are stable. In the eclipsed
conformation, H atoms are closest together. This gives higher repulsive forces
between them. As a result, eclipsed conformers are unstable. At any
moment, more molecules will be in staggered form than any other
conformation.
