Question
Chapter 14, Problem 5Q
Interpretation Introduction
Interpretation:
The behavior of the sample that was cooled and then remolded should be explained.
Concept introduction:
The melting point of a crystalline substance is the temperature at which the substance starts changes into the liquid phase. Melting point is directly associated with the presence of intermolecular forces like hydrogen bonding, dipole-dipole interactions. High molecular symmetry, large surface area, polarity is associated with high melting points.
A pure compound melt at a narrow range and compounds with impurities have a wide range of melting points. Melting points are determined by filling the organic compound into the capillary tube with one end sealed.

3. A pure white crystalline compound was found to melt at 131.5-132.0°C when taken on a
melting point apparatus, and on further heating, the liquid was found to start bubbling at ca.
155-160 °C. The capillary containing the melted compound was set aside to cool, and
resolidify. When the sample was retried using that same capillary, the sample melted at
120.6-154.5°C, along with some bubbling. What is the cause of the bubbles? Why is the
melting point so wide the second time? Explain by stating what you have learned in this
laboratory about melting points.
What are the different melting point apparatus that are available for routine analysis? Describe each.
