Using infrared spectroscopy, how can salicylic acid be difterentiated trom acetylsalicylic acid (aspirin)? Acetylsalicylic acid will have two carbonyl (C=O) stretches at approximately 1) 1700 cm1. It will possess one C=O stretch at about 1680 cm-1 for the carboxyl group which is present in both and one unique carbonyl stretch at 1725 cm 1 for the ester functional group. Salicylic acid will have two carbonyl (C=O) stretches at approximately 1700 2) cm. It will possess one C=O stretch at about 1680 cm for the carboxyl group which is present in both and one unique carbonyl stretch at 1725 cm1 for the ester functional group. 3) Acetylsalicylic acid and salicylic acid cannot be differentiated via IR spectroscopy as they have all the same stretches present. 4) Salicylic acid will have a unique aliphatic sp3-hybridized C-H at approximately 3150-3050 cm

Question
**Using infrared spectroscopy, how can salicylic acid be differentiated from acetylsalicylic acid (aspirin)?** 1. **Acetylsalicylic acid** will have two carbonyl (C=O) stretches at approximately 1700 cm⁻¹. It will possess one C=O stretch at about 1680 cm⁻¹ for the carboxyl group which is present in both and one unique carbonyl stretch at 1725 cm⁻¹ for the ester functional group. 2. **Salicylic acid** will have two carbonyl (C=O) stretches at approximately 1700 cm⁻¹. It will possess one C=O stretch at about 1680 cm⁻¹ for the carboxyl group which is present in both and one unique carbonyl stretch at 1725 cm⁻¹ for the ester functional group. 3. Acetylsalicylic acid and salicylic acid cannot be differentiated via IR spectroscopy as they have all the same stretches present. 4. **Salicylic acid** will have a unique aliphatic sp³-hybridized C-H at approximately 3150-3050 cm⁻¹.
