The correct answer is Option D.
Although conformers differ in potential energy and stability, the difference is so small that it does not allow their practical separation.

Try making Newman's Newman's diagram you will find, that infinite number of conformers can be made at different angles. In staggered form, there is much distance in between the groups, therefore, less strain.Same with option (c) happens. Staggered form cannot be separated out of system .

Which is not true regarding conformers of ethane?a)Theoretically infin...
Explanation:
The correct answer is option D: By precise experimental setup, staggered conformer can be separated out of the system. This is because it is not possible to separate the staggered conformer from the system by precise experimental setup.
Here is a detailed explanation of each option:
a) Theoretically, infinite conformers exist:
This statement is true. Ethane is a molecule with two carbon atoms connected by a single bond. The rotation around the carbon-carbon bond allows for the generation of different conformers. In theory, there are infinite conformations that can be obtained by varying the dihedral angle between the two carbon-hydrogen bonds.
b) Staggered conformer has lower torsional strain than eclipsed one:
This statement is true. In the staggered conformation, the carbon-hydrogen bonds on one carbon atom are as far away as possible from the carbon-hydrogen bonds on the other carbon atom. This results in a lower torsional strain, which is the energy associated with the eclipsing of these bonds. In the eclipsed conformation, the carbon-hydrogen bonds on one carbon atom are directly eclipsed with the carbon-hydrogen bonds on the other carbon atom, leading to a higher torsional strain.
c) Increasing temperature increases the percentage of eclipsed conformer:
This statement is true. At higher temperatures, the kinetic energy of the molecules increases, which allows for a greater number of rotations around the carbon-carbon bond. This results in a higher percentage of the eclipsed conformation as the molecules sample a wider range of conformations.
d) By precise experimental setup, staggered conformer can be separated out of the system:
This statement is false. It is not possible to separate the staggered conformer from the system by a precise experimental setup. The different conformations of ethane exist in equilibrium with each other and constantly interconvert. Although techniques such as spectroscopy can provide information about the relative populations of different conformers, it is not possible to completely separate the staggered conformer from the system.
In conclusion, option D is the correct answer as it is the only statement that is not true regarding the conformers of ethane.
