Vedclass · Answer

(B) The given Newman projection represents $n$-butane in a gauche conformation where the two methyl groups are at a dihedral angle of $60^{\circ}$.Rotating the front carbon $(C_2)$ by $120^{\circ}$ in the anticlockwise direction will move the front methyl group to a position where it is directly behind the back methyl group (eclipsed).When the two methyl groups are eclipsed,the conformation is known as the fully eclipsed conformation.

If the $C_2$ carbon in the given Newman projection is rotated by $120^{\circ}$ in the anticlockwise direction,what will be the resulting conformation of the $C_2-C_3$ bond?
