- A student was randomly given compounds E and F from the group of compounds below and asked to identify them according to their functional group. The student initially thought this to be easy, only to discover that he was embarking on some kind of Herculean task. If you were to correctly advise the student, which test will be most appropriate to distinguish compounds E and F. a. reaction with jones reagent b. iodoform test c. tollen's test d. brady's test (2,4-DNP) Note: I dont think it is tollens test or jones reagent. may you please explain this question in depth.Retrosynthesis is a method of chemical synthesis which involves “deconstructing” a target molecule into its readily available, simple starting materials in order to assess the best synthetic route. Research (the internet) and pick a molecule of interest to you, then work backwards to provide appropriate starting materials. Present your findings.Which of the following statements is TRUE regarding the reaction below? Options: The IR spectrum of the major organic product will show a broad absorption between 3000-3500 cm-1.
