{"knowledge_schema": {"broad_category": "Chemistry \u2192 Organic Chemistry \u2192 Spectroscopy", "refinement": "This problem involves the interpretation of NMR (Nuclear Magnetic Resonance) spectra to identify organic compounds based on their structural features and chemical environments.", "specific_scope": "The task is to analyze the provided 1H and 13C NMR data of a product derived from compound X and determine its identity among given candidates.", "goal": "Identify compound X by correlating the NMR spectral data with the structural characteristics of the candidate compounds."}, "summary": "This problem requires understanding NMR spectroscopy to identify an organic compound based on its spectral data. The provided 1H and 13C NMR signals give insights into the molecular structure of the product formed from compound X. By analyzing the chemical shifts and splitting patterns, we can deduce the structure of compound X and match it with the candidates provided. The correct identification of compound X is 2-(4-methylstyryl)oxirane, based on the spectral data."}
