Vedclass · Answer

(A) The initial structure shown is the fully eclipsed conformation of $n$-butane,where the two $CH_3$ groups are directly behind each other.Rotating the front carbon $(C_2)$ anticlockwise by $120^\circ$ around the $C_2-C_3$ bond moves the front $CH_3$ group to a position $60^\circ$ away from the back $CH_3$ group.This resulting conformation,where the bulky groups are at a dihedral angle of $60^\circ$,is known as the gauche conformation.

One of the configurations of $n$-butane is shown in the given figure. An anticlockwise rotation of $C_2$ around the $C_2-C_3$ bond by $120^\circ$ will lead to:
