Which of the following functional groups is likely to be present in a molecule that has peaks in the infrared spectrum at 1630-1820 cm^-¹ (strong, broad) and 1000-1250 cm^-¹; but does not have peaks at 3200-3650 cm^-¹?

The strong, broad peak at 1630-1820 cm^-1 indicates the presence of a carbonyl group (C=O), which is found in aldehydes, ketones, and esters. The absence of peaks at 3200-3650 cm^-1 rules out alcohols. The peak at 1000-1250 cm^-1 suggests the presence of a C-O bond, which is characteristic of esters.
