Question
**Question 17 of 21** An IR spectrum of an unknown compound is shown below. Predict the principal functional group present in this compound. **IR Spectrum Graph:** - The x-axis is labeled "Wavenumber (cm⁻¹)" and ranges approximately from 4000 to 500 cm⁻¹. - The y-axis is labeled as a percentage transmittance. - There is a significant peak indicating absorption between 1700 and 1750 cm⁻¹, which typically corresponds with a carbonyl group (C=O) stretch. **Options:** A) Amide B) Amine C) Carboxylic acid D) Alcohol E) Aldehyde **Analysis:** The presence of a peak in the region between 1700 and 1750 cm⁻¹ suggests a functional group featuring a carbonyl bond, commonly found in aldehydes and carboxylic acids.
