**Enantiomers** are stereoisomers that:
AAre identical molecules
BAre non-superimposable mirror images of each other (rotate plane-polarised light in opposite directions)
CHave different molecular formulae
DAre different functional groups
Answer & Solution
Correct answer: B. Are non-superimposable mirror images of each other (rotate plane-polarised light in opposite directions)
Enantiomers: same connectivity, opposite 3D arrangement at chiral centre(s); mirror images that cannot be overlaid. They have identical physical properties except optical rotation (dextro +, laevo −) and reactions with other chiral molecules.
