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

Question

Quizplus · Accepted Answer

The carbonyl stretching frequency for acid chlorides is higher, around 1800 cm^-1, due to the electron-withdrawing effect of the chlorine atom, which increases the double bond character of the carbonyl group, leading to a higher stretching frequency.
