Question

What can be said about the shape of the infrared stretch of the o-h functional group in a carboxylic acid.?

Answer 1

Step-by-step explanation:

Since carboxylic acids have an -OH group, they can form dimers by hydrogen bonding (see on attachment).

Because of this property of forming dimers, the hydrogen bond is stronger than in alcohols and phenols. This translates into a wider absorption band and more displaced towards lower frequencies.
