Is it possible to isolate pure staggered ethane or pure eclipsed ethane at room temperature?

Text Solution

Verified by Experts

The energy differences between staggered and eclipsed froms of ethane is just `12.55 "kJ mol"^(-1)` which is easily met by collisions of the molecules at room temperature. Therefore, it is not possible to isolate either pure staggered or pure eclipsed ethane at room temperature.
