Quizplus · Accepted Answer

The IR shows a strong, sharp peak at around 1700 cm^-1, which indicates the presence of a carbonyl group. The absence of a broad peak around 3200-3500 cm^-1 rules out the presence of an alcohol or carboxylic acid group. The absence of a peak around 2700-2900 cm^-1 rules out the presence of an aldehyde group. The absence of a peak around 3300 cm^-1 rules out the presence of an amine group. Therefore, the compound is a ketone.
