Question
Chapter 29, Problem 29.7QAP
Interpretation Introduction
(a)
Interpretation:
The effect of increase in the flow rate on the elution time of supercritical carbon dioxide in an SFC experiment is to be explained at constant pressure and temperature.
Concept introduction:
The time that falls in between the entry of the solute into the column and the starting of elution of the solute is termed as the elution time. There are in total three factors that affect the elution time such as flow rate, pressure and temperature.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there
are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from
the arrow.
• Is the student's transformation possible? If not, check the box under the drawing area.
• If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts,
inorganic reagents, or other important reaction conditions above and below the arrow.
• You do not need to balance the reaction, but be sure every important organic reactant or product is shown.
