The correct statement regarding ethane conformation is :
- ARotation around carbon-carbon bond in ethane molecule is not possible, because ethane molecule contains a pi $(\pi)$ bond between the carbon and carbon and ethane has very low melting point.
- BRotation around carbon-carbon bond in ethane molecule is not possible, because ethane molecule contains both sigma $(\sigma)$ bond, and pi $(\pi)$ bond between the carbon and carbon.
- ✓Rotation around carbon-carbon bond in ethane molecule is possible because of cylindrical symmetry of sigma $(\sigma)$ bond between carbon-carbon atoms
- DRotation around carbon-carbon bond in ethane molecule is not possible, because ethane molecule contains both sigma $(\sigma)$ bond and pi $(\pi)$ bond between the carbon and carbon and ethane has very high boiling point.
