Assertion : 1,3-dichlorocyclopentane can show optical isomerism.
Reason : Compound which have POS or COS can never show optical isomerism.
Options:
Answer:
C
Solution:
Assertion is true: 1,3-dichlorocyclopentane can exist in forms having chirality, so optical isomerism is possible.
Reason is false: Presence of a plane of symmetry (POS) or centre of symmetry (COS) generally makes a molecule achiral, but the statement says such compounds can never show optical isomerism, which is too absolute.
Optical isomerism depends on the overall chirality of the molecule.
Hence, Assertion is true but Reason is false.
