# In the given conformation, if $C_2$ is rotated $C_2 -C_3$ bond anticlockwise by an angle of $120^{\circ}$ then the conformation obtained is

(a) Fully eclipsed conformation

(b) Partially eclipsed conformation

(c) Gauche conformation

(d) staggered conformation

The conformation obtained will be gauche conformation.
Gauche refers to confrontational isomers.
where two vicinal groups are separated by a $60^{\circ}$ torsion angle.
Hence c is the correct answer.
