Vedclass · Answer

(B) The stability of $n$-butane conformers follows the order: $Anti-staggered > Gauche > Eclipsed > Fully eclipsed$. In the $anti-staggered$ conformation,the two bulky methyl groups are at a dihedral angle of $180^{\circ}$,which minimizes steric repulsion between them. In the $gauche$ conformation,the methyl groups are at a dihedral angle of $60^{\circ}$,leading to some steric hindrance. In the $eclipsed$ and $fully eclipsed$ conformations,the groups are closer,leading to significant torsional and steric strain. Therefore,the $anti-staggered$ conformer is the most stable.
