Chemistry - STEREO ISOMERISM Question with Solution | TestHub

A compound is chiral if it has an asymmetric (sp³) carbon with four different groups.

Option (A): Central carbon has two identical groups → achiral.

Option (B): Carboxylic acid (–COOH) carbon is sp² planar, so no chirality.

Option (C): Central carbon is attached to Cl, H, CH₃, and C₂H₅ → all different groups.

Hence it forms a chiral center (asymmetric carbon).

Option (D): Has internal symmetry (meso form) → optically inactive.

Therefore only (C) shows chirality.
