Which of the following statements concerning the conformers of butane is true?
A) Unlike ethane, all butane conformers are classified as eclipsed.
B) The lowest energy conformer of butane is the gauche conformer.
C) There is more torsional strain in the anti conformer than in the totally eclipsed conformer.
D) The eclipsed and totally eclipsed conformers have the same amount of nonbonded strain.
E) The gauche and anti conformers differ primarily in the amount of nonbonded strain present.
Conformers
Different spatial arrangements of atoms in a molecule that can be converted into one another by rotation around single bonds.
Butane
A gaseous hydrocarbon with the formula C4H10, existing in two isomeric forms and used as a fuel and a refrigerant.
Torsional Strain
A type of strain in molecules that occurs when atoms in a molecule are placed such that they cause repulsion by being in close proximity, often linked to bond angles and rotation around bonds.
