Question

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.a. Weak?

b. Strong?
c. Very broad?
d. Comes to a double point?
e. Sharp?

Answer 1

Answer: Strong (b)

Step-by-step explanation:

INFRARED ACTIVE BONDS

Not all covalent bonds display bands in the IR spectrum. Only polar bonds do so. These are referred to as IR active.

The intensity of the bands depends on the magnitude of the dipole moment associated with the bond in question:

Strongly polar bonds such as carbonyl groups (C=0) produce strong bands.
