Correct option is (a) Potential energy of C1 > C2
A torsion angle or dihedral angle, is formed by three constructive bonds in a molecule and defined by the angle created between the two outer bonds.
Angle between ACC plane & BCC plane called dihedral angle.
Here.
have zero dihedral angle. because clc— c— cl are in one plane---
* Potential energy of C1 > C2 is wrong statement. Because, potential energy of staggered form is always less than potential energy of eclipse forms.
