Conformational isomersHardQuestion 810010
Question
Conformational isomers (conformers) of ethane differ in:
- ARotation about C−C single bond (staggered vs eclipsed)Correct
- BCarbon skeleton
- CFunctional group
- DMolecular formula
Correct answer
Rotation about C−C single bond (staggered vs eclipsed)
Explanation
Conformers arise from rotation about C−C single bonds. Staggered (anti/gauche) conformations are lower energy than eclipsed. Newman projections are used to visualise conformers.
