Question

The dihedral angle hch in staggered conformation of c2h6 is

Answer 1

In the staggered conformation, the C-H bonds on the rear carbon lie between those on the front carbon with dihedral angles of 60 degrees.

Answer 2

Concept: A staggered conformation is a chemical conformation of an ethane-like molecule in which the substituents are separated to the greatest extent possible. This necessitates a 60° torsional angle.

Given: $C_{2} H_{6}$

To find: Dihedral angle HCH in staggered conformation of $C_{2} H_{6}$

Solution:

$C_{2} H_{6}$ is ethane

Refer the figure below

Therefore, the dihedral angle HCH in staggered conformation of $C_{2} H_{6}$ is 60°
