Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Optical Isomerism: Compound (C) has a chiral carbon center (the ring carbon bonded to the $-C{H}_3$ group) surrounded by four different groups, making the molecule optically active.

Geometrical Isomerism: The exocyclic double bond $(=CHCl)$ has restricted rotation and is attached to two different groups on both ends ($-H$ and $-Cl$ on one carbon, and two unsymmetrical ring pathways on the ring carbon).

Because it satisfies both criteria simultaneously, Compound (C) shows both geometrical and optical isomerism.
