Which of the following statements about the conformers that result from rotation about the C2-C3 bond of butane is correct?

Question

Quizplus · Accepted Answer

The correct statements about the conformers resulting from rotation about the C2-C3 bond of butane are not listed among the options provided. Specifically, the highest energy conformer is the one where the methyl groups are eclipsed by each other, not by hydrogens (A is incorrect). The gauche conformer is not eclipsed but rather staggered with a dihedral angle of 60 degrees (B is incorrect). Steric strain is actually present in eclipsed conformers due to the repulsion between electron clouds of adjacent atoms or groups (C is incorrect). An eclipsed conformer is less stable than a staggered conformer due to this steric strain and torsional strain, making D incorrect.
