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.

- 6.0 mL of cyclohexanol, 8 mL of 85% phosphoric acid, and 10 drops of sulfuric acid are added to a 50-mL round-bottom flask with boiling chips, and the mixture is distilled into an ice-cooled receiver. The distillate is in the form of a colorless bi-phasic mixture. The cyclohexene upper layer is removed from the water layer, and dried over anhydrous calcium chloride. Isolated is cyclohexene as a clear and colorless foul-smelling liquid. Weighing data is given below. Gross mass: 51.24 g Tare mass: 48.04 g Product mass: 3.2g Question: Calculate the theoretical mass of the cyclohexene product, bearing in mind that the cyclohexanol starting material was measured by volume, not by mass (so you must use the density of cyclohexanol to convert milliliters to grams, before calculating the number of moles).
