Eclipsed Butane. 1) fully eclipsed, when the methyl groups eclipse each other; Such degeneracy is broken in butane, which has two different eclipsed conformations and two different staggered conformations.
Eclipsed conformations ii and vi have repulsive dispersion forces arising from the eclipsed methyl groups and hydrogen atoms. Dihedral angle scan of butane (.xyz) animations created by pier alexandre champagne.

With Butane, Not All Eclipsed Conformations Are Of The Same Energy, And Not All Staggered Conformations Are Of The Same Energy.
The totally eclipsed butane, due to the two eclipsing methyl groups at 0° dihedral angle, has the highest energy (19 kj/mol) and is the most unstable form.
The Correct Option Is A.

Thus we see that there are four possible “extreme” conformations of butane:
