How many conformations can an alkane have by rotation about single bonds?
AIndented
BInfinite
CInflected
DInflated
Answer & Solution
Correct answer: B. Infinite
1. Rotation is continuous, not stepwise.
2. Every angle gives another arrangement.
3. Alkanes can have infinite number of conformations by rotation around carbon to carbon single bonds.
4. So the answer is infinite.
