317885 Assertion :
Staggered conformation of ethane is \(1.25 \mathrm{~kJ} \mathrm{~mol}^{-1}\) more stable than the eclipsed conformation.
Reason :
The two conformations of ethane cannot be separated at room temperature.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
