💡 Solution & Explanation

# Analysis of Enantiomer Properties **Statement (1): "They have same physical properties"** ✓ **TRUE** — Enantiomers have identical melting points, boiling points, density, solubility in achiral solvents, etc., because they differ only in spatial orientation. **Statement (2): "They are mirror images of each other"** ✓ **TRUE** — This is the definition of enantiomers. They are non-superimposable mirror images (like left and right hands). **Statement (3): "Equimolar mixture of enantiomers is optically active"** ✗ **FALSE** — An equimolar mixture of two enantiomers is called a **racemic mixture** (or racemate). Since both enantiomers rotate plane-polarized light in equal but opposite directions, their optical rotations cancel out completely. The mixture is therefore **optically inactive** (rotation = 0°). **Conclusion:** Statement (3) is **not true** about enantiomers. A 50:50 mixture (racemic) is optically *inactive*, not active. **Answer: Option (3)**
