{"knowledge_schema": {"broad_category": "Chemistry \u2192 Organic Chemistry \u2192 Isomerism", "refinement": "This problem focuses on the types of isomerism, specifically geometric isomerism and enantiomerism, in organic compounds.", "specific_scope": "The task involves identifying which compound exhibits geometric isomerism and which compound exhibits enantiomerism among the given options.", "goal": "Determine the correct compounds that demonstrate geometric isomerism and enantiomerism based on their structural characteristics."}, "summary": "In this problem, we are examining two types of isomerism in organic compounds: geometric isomerism and enantiomerism. Geometric isomerism occurs in compounds with restricted rotation around a double bond, such as 2-butene, which can exist as cis and trans isomers. Enantiomerism occurs in compounds that have a chiral center, such as 2-butanol, which can exist as non-superimposable mirror images. The correct answer identifies 2-butene as the compound exhibiting geometric isomerism and 2-butanol as the compound exhibiting enantiomerism."}
