The IR spectrum shows characteristic bands that suggest the presence of hydroxyl and carbonyl groups, while the NMR spectrum provides information about the hydrogen environments in the molecule. By analyzing the data, we can compare the spectral features with the candidates provided to determine the correct compound. The goal is to match the spectral data with one of the four candidates: ethyl 4-aminobenzoate, 4-aminophenyl propionate, N-(4-ethoxyphenyl)formamide, or 3-ethoxybenzamide."}
