Question

Write the possible conformation of ethane and explain which is more stable?​

Answer 1

Answer:

The eclipsed conformation of ethane is less stable than the staggered conformation by 3 kcal/mol. The staggered conformation is the most stable of all possible conformations of ethane, since the angles between C-H bonds on the front and rear carbons are maximized at 60 degrees

Answer 2

Answer:

Rotations around C-C single bond in Ethane forms infinite structures are called Conformations of Ethane. And the phenomenon is called Conformational Isomerism.

Conformations of Ethane are

1. Staggered Conformation
2. Eclipsed Conformation

Staggered Conformation:- Hydrogen atoms on both the carbons are apart from each other (more stable).

Eclipsed Conformation:- Hydrogen atoms on both the carbons are close to each other (less stable).

• Staggered form is more stable than eclipsed form due to less repulsions between Hydrogen atoms.
