Which of the following functional groups is likely to be present in a molecule that has peaks in the infrared spectrum at 3200-3650 cm−¹ (strong), but does not have peaks at 1630-1820 or 1000-1250 cm−¹ A) alcohol B) aldehyde or ketone C) ether D) ester

The presence of peaks in the 3200-3650 cm^-1 range in the infrared spectrum indicates the presence of O-H stretching, which is characteristic of alcohols. The absence of peaks in the 1630-1820 cm^-1 range rules out carbonyl groups (found in aldehydes, ketones, and esters), and the absence of peaks in the 1000-1250 cm^-1 range suggests the absence of C-O stretching found in ethers and esters.
