The 1H and 13C NMR spectra provide specific chemical shifts and splitting patterns that correspond to different functional groups and molecular environments. By analyzing the spectral data and comparing it with the candidates, we can deduce that compound Y is phenylacetaldehyde, as it matches the expected signals from the reaction with mCPBA."}
