Question
Chapter 9, Problem 5Q
Interpretation Introduction
Interpretation:
The reason for the separation of compounds as a mixture instead of individual components should be speculated.
Concept introduction:
A separation technique used for the segregation of components of chemical mixture based on the difference between the adsorption of different components in the stationary and mobile phase is called column chromatography.
It is used for purification or segregation of compounds. It consists of two phases namely:
- Stationary phase (solid)
- Mobile phase (generally liquid)
Silica gel is commonly used as the stationary phase.

How many signals do you expect in the H NMR spectrum for this molecule?
Br
Br
Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red.
Note for advanced students: In this question, any multiplet is counted as one signal.
Number of signals in the 'H NMR spectrum.
For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to
the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in top
molecule
For the molecule in the bottom drawing area, highlight in red any other H atoms that will
contribute to the same signal as the H atom already highlighted red.
If no other H atoms will contribute, check the box at right.
No additional Hs to color in bottom

Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure.
