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.

2. Consider the data below to answer the following questions.
Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and
aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid.
Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin
is treated with aqueous base the original carbonyl compound is isolated.
