Interpretation:
For distinguishing the pairs (a), (c), (d), (e), (g), and (i) given in problem 2.46, the key IR absorption bands are to be predicted.
Concept introduction:
Infrared spectroscopy is a simple, instrumental technique, which helps to determine the presence of various
It depends on the interactions of atoms or molecules with the
