Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Option (A): Both compounds have 2 stereoisomers (2-chlorobutane has 1 chiral center $\to 2^1=2$; but-2-ene exhibits cis/trans isomerism $\to 2$).

Option (B): Both compounds have 2 stereoisomers (2-chlorobutane has 1 chiral center $\to 2$; the allene penta-2,3-diene is chiral due to perpendicular planes $\to 2$ enantiomers).

Option (C): Both constitutional isomers have exactly 1 chiral center each, resulting in 2 stereoisomers ($2^1=2$) for both compounds.

Option (D): The first compound is unsymmetrical with 2 chiral centers (4 stereoisomers), while the rigid bicyclic compound has a plane of symmetry (1 stereoisomer).
