Question

The purity of an organic compound is determined by:

• A. chromatography
• B. crystallisation
• C. melting or boiling point
• D. both (a) and (c).

Answer 1

The correct option is C melting or boiling point

The pure organic compound has characteristics physics properties such as refractive index, melting point, boiling point, crystalline structure.

Thus to identify the purity of the organic compound, the melting and boiling point can be used.

The impure organic compound will have a non-specific melting point and boiling point.
