The 1630-1800 cm^-1 region can be used to distinguish between alcohols and carboxylic acids.

Question

Quizplus · Accepted Answer

The 1630-1800 cm^-1 region corresponds to the carbonyl stretching vibrations for both alcohols and carboxylic acids. However, carboxylic acids will also have additional peaks around 2500-3000 cm^-1 for the O-H stretch. Therefore, the 1630-1800 cm^-1 region can be used to distinguish between alcohols (which lack the O-H stretch) and carboxylic acids (which have the O-H stretch in addition to the carbonyl stretch).
