Question
Chapter 4.4, Problem 4E
Interpretation Introduction
Interpretation:Efficiency of packed fractional distillation column is more than that of unpacked column for separation of two closed boiling liquids should be determined.
Concept introduction:Fractional distillation is separation technique that separates various fractions of components in mixture. This process is based on vaporization of one or more fractions or parts of mixture. It is used to separate components of mixture that have difference in boiling points less than

When performing a melting point on a solid compound using a melting point apparatus, two melting point determinations were made. One sample, which was 1 mm in height in the capillary, possessed a melting point of 200.0-200.5°C. The other sample was 25 mm in height.
