The provided 1H-NMR and 13C-NMR data give insights into the number of hydrogen and carbon environments, their chemical shifts, and splitting patterns. The goal is to analyze this data to deduce the structure of compound Y (C10H10O) and match it with one of the given candidates. The correct answer is identified as 2-(3-methylstyryl)oxirane."}
