An IR spectrum of an unknown organic molecule having the formula C₃H₆O₂ reveals strong absorptions at 2500-3400 cm^-¹, 1715 cm^-¹, and 1230 cm^-¹.To what class of compounds does the unknown belong?

Question

Quizplus · Accepted Answer

The strong absorptions at 2500-3400 cm^-1, 1715 cm^-1, and 1230 cm^-1 are characteristic of carboxylic acids. The broad absorption in the 2500-3400 cm^-1 range is due to O-H stretching, the 1715 cm^-1 absorption is indicative of the C=O stretching of a carboxylic acid, and the 1230 cm^-1 absorption can be associated with C-O stretching.
