Hyperconjugation is proposed to explain why ethane prefers its
AEclipsed conformation
BBoat conformation
CStaggered conformation
DPlanar conformation
Answer & Solution
Correct answer: C. Staggered conformation
In the staggered form each C-H bond lines up with an antibonding orbital on the other carbon, maximising hyperconjugative stabilisation.
