MCQ
Which conformation of ethane has the lowest potential energy?
- AEclipsed
- BSkewed
- ✓Staggered
- DAll will have equal PE
✓
Answer
Correct option: C.
Staggered
(c) Staggered
Explanation: In staggered conformation of ethane, any two H -atoms on adjacent C -atoms are as far apart as possible. As a result, the repulsions between the electron clouds of $\sigma$-bonds of two non bonded H -atoms are minimum and hence stability is maximum.
