Question

Quizplus · Accepted Answer

The IR spectrum indicates the presence of a broad O-H stretch (2800-3300 cm^-1), a C-H stretch (2950 cm^-1), and a carbonyl group (1740 cm^-1). The ^13C NMR data shows a quartet at 17.3 ppm (indicative of a CH3 group next to an oxygen), a singlet at 44.3 ppm (indicative of a saturated carbon), and a singlet at 210.5 ppm (indicative of a carbonyl carbon). The structure in option A, which is acetic acid, matches these characteristics, including the presence of a carboxylic acid group (OH attached to a carbonyl carbon), which is consistent with the IR and NMR data provided.
