NEET Chemistry Alkanes MCQ Question
Consider a diagram showing different spatial arrangements of a butane molecule due to rotation around one of its C-C single bonds. Which of the following statements about these conformations is correct?

The staggered conformation is the most stable due to minimal torsional strain.
The eclipsed conformation is the most stable because it has the highest potential energy.
Conformational energy varies due to the presence of pi bonds in alkanes.
All conformations of alkanes have the same energy due to free rotation.
Correct Answer
Detailed Explanation
Alkanes can have infinite conformations due to rotation around C-C single bonds. The staggered conformation is more stable as it has minimal torsional strain compared to the eclipsed conformation.
