Question
Chapter 27, Problem 27.24QAP
Interpretation Introduction
Interpretation:
The reason and the change in the retention times for the three compounds is to be stated.
Concept introduction:
Retention time is the amount of time that arises in between the sample introduction and the maximum of the response. It is the time taken by the solute to completely pass through the column. The retention time is less for non-polar solvents, whereas it is relatively large for polar solvents.
