Expert Solution

Step 1-Introduction

The polar compounds are known for the presence of polar functional groups such as alcohol ( $- O H$ ) or carboxylic acid ( $- C O O H$ ). The non-polar compound should be from such reactive functional groups or groups with the replaceable hydrogen atom.

Separation of the individual components of a mixture can be best accomplished by chromatographic techniques. One such technique is thin layer chromatography (TLC). The separation of components is based on the principle of their partition between the stationary phase and the mobile phase.
