Among the Newman and Sawhorse projections for the eclipsed and staggered conformations of ethane, which of these conformations is more stable and why?
Options
- AThe eclipsed conformation in the Newman projection is more stable because it has lower steric hindrance.
- BThe eclipsed conformation in the Sawhorse projection is more stable because it has lower steric hindrance.
- CThe staggered conformation in the Sawhorse projection is more stable because it has higher steric hindrance.
- DAmong staggered and eclipsed conformation of ethane, staggered conformation is more stable than eclipsed confo
Correct answer
D. Among staggered and eclipsed conformation of ethane, staggered conformation is more stable than eclipsed confo
Step-by-step solution
Correct Option is : (D) Among staggered and eclipsed conformation of ethane, staggered conformation is more stable than eclipsed conformation as in staggered form, the electron clouds of carbon-hydrogen bonds are as far apart as possible. Thus, there are minimum repulsive forces, minimum energy/ torsional strain and maximum stability of the molecule
