NEET Chemistry Alkanes MCQ Question
Type: MCQ-diagram based-Hard-Class 11
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?
A
The staggered conformation is the most stable due to minimal torsional strain.
B
The eclipsed conformation is the most stable because it has the highest potential energy.
C
Conformational energy varies due to the presence of pi bonds in alkanes.
D
All conformations of alkanes have the same energy due to free rotation.
Correct Answer
Option A
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.
