Which purification method is generally used for a high boiling organic liquid compound, which decompose below its boiling point?
Show Hint
Match the distillation technique to the properties of the substance:
- \textbf{Simple Distillation:} Separate liquids with large differences in boiling points (> 25 °C).
- \textbf{Fractional Distillation:} Separate liquids with small differences in boiling points.
- \textbf{Vacuum Distillation:} Purify liquids that decompose at or near their normal boiling point.
- \textbf{Steam Distillation:} Purify liquids that are immiscible with water and volatile in steam.
