Which of the following is correct regarding stability of conformations of n-butane about `C_(2)-C` bond
Anti (I) gauche (II) partially eclipsed (III) fülly eclipsed (IV)

A

I `gt` II `gt` III `gt` IV

B

I `gt` II `gt` IV `gt` III

C

IV `gt` III `gt` II `gt` I

D

IV `gt` II `gt` I `gt` III

Text Solution

Verified by Experts

The correct Answer is:
A
Dihedral angle is Inversely praprotional to stability of conformer. Dihedral angles for fully eclipsed (IV), gauche (II), partially eclipsed (III) and Anti (I) are 0.60,120,180 respectively
