The 1H and 13C NMR signals provide information about the number of hydrogen and carbon atoms in the compound, as well as their environments. By analyzing the chemical shifts and splitting patterns, we can deduce the structure of compound Y, which is identified as phenylacetaldehyde based on the provided data."}
