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

c) Very broad

Explanation:

The options for this question are:

a) Weak?

b) Strong?

c) Very broad?

d) Comes to a double point?

e) Sharp?

We have to keep in mind that the O-H group has the ability to form intermolecular hydrogen bonds. When this happens the stretch O-H can be affected by this phenomenon. In the IR spectrum can be observed a very broad signal due to this. Therefore when we have functional groups like alcohol or acids we can expect this broad signal.
