Which of the following compounds gives an infrared spectrum with peaks at 3000-3500 cm^-1 and ~1750 cm^-1?

Question

Quizplus · Accepted Answer

The IR peaks at 3000-3500 cm-1 are indicative of an -OH or -NH stretch, while the peak at ~1750 cm-1 is indicative of a carbonyl (C=O) stretch. Among the given compounds, only compound 3 (ethanol) contains both an -OH group and a carbonyl group (in the form of an ester). Therefore, compound 3 is the best choice for the given IR spectrum.
