allerySpatial arrangements interconverted by rotation about a single bond are called:
AConformations
BConfigurations
CConstitutions
DContractions
Answer & Solution
Correct answer: A. Conformations
1. No bond is broken in the interconversion.
2. Only rotation about a single bond is involved.
3. Spatial arrangements converted into one another by rotation around a carbon to carbon single bond are called conformations.
4. So the answer is conformations.
