Question

Staggered conformation occurs at the dihedral angle of

• A. $0^0,{120}^0,{240}^0$
• B. ${90}^0,{180}^0,{240}^0$
• C. ${60}^0,{180}^0,{300}^0$
• D. ${90}^0,{180}^0,{300}^0$

Answer 1

The correct option is C ${60}^0,{180}^0,{300}^0$

Staggered conformation occurs at a dihedral angle of ${60}^0$, ${180}^0$ and ${300}^0$ as can be seen from the figure.
