Question

Three Types of conformation of Ethane

Answer 1

Ethane Conformations. Although there are seven sigma bonds in the ethane molecule, rotation about the six carbon-hydrogen bonds does not result in any change in the shape of the molecule because the hydrogen atoms are essentially spherical.

Answer 2

Conformations of Ethane. While there are an infinite number ofconformations about any sigma bond, in ethane two particular conformers are noteworthy and have specialnames. In the eclipsed conformation, the C-H bonds on the front and back carbons are aligned with each other with dihedral angles of 0 degrees.
