Respuesta :
The form of ethane that has the least torsional strain is the staggered conformation.
Explanation:
1. In ethane, the carbon-carbon single bond allows rotation, leading to different conformations.
2. Torsional strain occurs due to the repulsion between electron clouds of bonded atoms when they are forced too close together.
3. In the staggered conformation, the hydrogen atoms are as far apart as possible, minimizing the torsional strain.
4. The skew boat, eclipsed, and boat conformations lead to increased torsional strain compared to the staggered conformation.
5. Therefore, the staggered conformation of ethane is the most stable and has the least torsional strain among the options provided.
