Question
Chapter 26, Problem 26.3QAP
Interpretation Introduction
Interpretation:
In the chromatography, the list of the variables that cause zone broadening needs to be determined.
Concept introduction:
The zone broadening in chromatography is caused due to the several effects. These effects are the diffusion process and the transfer of the solutes between the mobile and stationary.

When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M* = 163 m/z)
is formed. In the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm. The 13C NMR and DEPT spectra
are provided. Draw the structure of the product as the resonance contributor lacking any formal charges.
