Question

The dihedral angle between the hydrogen atoms of two methyl groups in staggered conformation of ethane is :

• A. ${120}^{\circ }$
• B. ${180}^{\circ }$
• C. ${60}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

The correct option is C ${60}^{\circ }$

The dihedral angle between the hydrogen atoms of two methyl groups in staggered conformation of ethane is ${60}^{\circ }$. So, the correct answer is option (c).
