Question
Chapter 15, Problem 15.17P
Interpretation Introduction
Interpretation:
The frequencies of the stretching vibrations indicated in each of the given molecules are to be estimated by using Table 15-2.
Concept introduction:
The frequencies of the stretching vibrations are estimated from the type of bond and the frequency range given for that bond. Also frequency range for the given type of bond is identified by the compound class to which that bond resembles in the molecule.
