Find out the number of compounds which can show both optical as well as geometrical isomerism?

Question

TestHub · Accepted Answer

Total compounds: 6 compounds show both geometrical isomerism (GI) and optical isomerism (OI), specifically: (ii), (iv), (v), (vi), (vii), and (viii).

Alkenes (ii) & (iv): Show GI across the exocyclic double bond and OI due to the asymmetric chiral center on the ring.

Biphenyl (v): Shows OI via hindered ring rotation (atropisomerism) and GI through the substituted alkene side chain.

Acyclic chain (vi): Shows GI at the internal $- C H = C H -$ bond and OI from its two distinct chiral centers.

Cyclic rings (vii) & (viii): Show GI via cis/trans substituent arrangements and OI due to a complete lack of structural symmetry.
