Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Explain Question:

Identify the molecule that is chiral and stable enough to be resolved into its enantiomeric forms.

Concept:

Chirality, Amine Inversion, Symmetry Elements (POS/COS)

Solution:

• Option 1: This amine (H, D, CH₃ ) undergoes rapid Amine Inversion, preventing resolution at room

temperature.

• Option 2: Trans-1,4-dimethylcyclohexane possesses a POS and Center of Symmetry (COS), making it

achiral.

• Option 3: This lactide has a Center of Symmetry (COS) in this specific configuration, making it a nonresolvable

meso compound.

• Option 4: This cyclic structure is chiral as it lacks any internal symmetry (POS or COS), making it the

resolvable compound.

Final Answer: Option (D)
