Conformations are not superimposable in three dimensions and can be characterized by their dihedral angles, the angle between two planes formed by atom1-atom2-atom3 and atom2-atom3-atom4 in a sequence of atoms, atom1-atom2-atom3-atom4. The dihedral angle can also be seen as the angle between the two vectors formed by atom2→atom1 and atom3→atom4. Rotamers are conformers that differ by rotation about only a single σ bond. That is, only one dihedral angle will be different between rotamers.
what are rotamers
what is the axis of symmetry in configurational isomers

but there is no harm in knowing .. because we have actually studied eclipsed form and staggered form of ethane and these two are actually rotamers :)

thanks Ankit
please also explain the axis of symmetry
i only know about the point and the plane of symmetry but what is this axis of symmetry

Hey its asked in iit 2008 about the axis of symmetry
Please someone help

axis of symmetry is a line about which if you rotate the compound
you should get the same compound at some angle of rotation (angle should not be a multiple of 2nπ)
