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.

Introduction Perhaps the cleanest method of conducting an oxidation is by catalytic oxidation, since this minimizes the problem of removal of unwanted by- products. However, the conditions used are often vigorous and require the use of specialized equipment. By comparison, the product of a "chemical" oxidation may be more difficult to purify due to the presence of the reduced form of the oxidizing agent and potential "tars" that may arise from "over- oxidation". Because chemical oxidation can be carried out using conventional equipment they are more popular. dissolving sodium or potassium dichromate in acid is a commonly used oxidizing agent, being classed as a relatively powerful oxidant and having water soluble by-products (Cr III salts). Sulphuric acid is generally used if the material to be oxidized is water soluble and glacial acetic acid is used if it is Chromic acid, prepared in-situ by not. Alcohols are readily oxidized to…
