Per NCERT §9.2.4, the STAGGERED form of ethane is more stable than ECLIPSED for which reason?
ALowest steric strain
BLowest torsional strain
CHighest hydrogen bonds
DHighest dipole
Answer & Solution
Correct answer: B. Lowest torsional strain
NCERT §9.2.4: in staggered, C-H electron clouds are farthest apart, so torsional (electron-electron repulsion) strain is minimum.
