While the carbonyl stretching frequency for simple aldeydes, ketones, and carboxylic acids is about 1710 cm^-1, the carbonyl stretching frequency for esters is about ________.

Question

Quizplus · Accepted Answer

The carbonyl stretching frequency for esters is typically around 1735 cm^-1, which is slightly higher than the frequency for simple aldehydes, ketones, and carboxylic acids. This is because the presence of the ester functional group (C=O-O) causes a slight increase in the bond strength, which results in a higher stretching frequency. Option C is the closest value to 1735 cm^-1, making it the best choice.
