Answer: (B) . \textbf{Answer:} (b) \textbf{Solution:} The eclipsed conformation of ethane is the least stable (maximum torsional strain) and corresponds to a dihedral (torsion) angle of , where the C-H bonds on the two carbons fully overlap.
- A.
- B.✓
- C.
- D.
Correct Answer
(B)
Solution & Explanation
\textbf{Answer:} (b) \textbf{Solution:} The eclipsed conformation of ethane is the least stable (maximum torsional strain) and corresponds to a dihedral (torsion) angle of , where the C-H bonds on the two carbons fully overlap. The staggered conformer () is the most stable.
