Arrange the test samples in order of increasing solubility in water? Explain briefly. -Ethylamine, Diethylamine, Aniline 3. Arrange the test samples in order of increasing basicity? Explain briefly. -NaOH, Ethylamine, AnilineThe compound acetophenone has a very similar molar mass to that of benzoic acid and benzamide. However, acetophenone has a much lower m.p. (20 °C) than both such that, by contrast, it is a liquid at room temperature. By considering intermolecular forces and comparing functional group structure, account for this big difference in physical properties.What reagents would you use to chemically extract benzoic acid and valeric acid? Or can it not be chemically extracted? The image shows the compound structure.
- List at least three (3) physical or spectroscopic methods that can be used to differentiate between benzophenone and benzhydrol. Explain how you would differentiate them.Restate the paragraph. The main objective of the laboratory activity was to make aspirin also known as acetylsalicylic acid in its scientific name. It was successfully done as aspirin was synthesized using the combination of salicylic acid and acetic anhydride. In this reaction, salicylic acid's hydroxyl group on the benzene ring interacted with acetic anhydride to generate an ester functional group. This is an esterification reaction that produces acetylsalicylic acid. Sulfuric acid was utilized as a catalyst to start the esterification reaction. Some unreacted acetic anhydride and salicylic acid, as well as sulfuric acid, aspirin, and acetic acid, remained in the solution after the reaction was completed. The process of crystallization was used to obtain pure crystals of a substance from an impure mixture. Upon completion of the lab, analysis, and calculations, , it is evident that the synthesis of aspirin is possible using these methods but that the yield will be relatively lowExplain the general procedure for the laboratory preparation of the synthesis of Aniline from benzoic acid. (paragraph form) Explain the chemistry behind the synthesis of Aniline from benzoic acid. (paragraph form)
