Question

In the given conformation $C_2$ is rotated about $C_2$-$C_3$ 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

Answer 1

The correct option is C Gauche conformation

When $C_2$ is rotated about $C_2$-$C_3$ bond anticlockwise by an angle of ${120}^{\circ }$ then the conformation obtained is Gauche conformation. Hence, the correct answer is option (c).
