comparative analysis of organic compounds were done on various unknown samples labelled as A, G, N, U, Y. After multiple solubility tests, the following observations were recorded: I. Sample G dissolved in water and produced litmus paper results: Red → Red; Blue → Red II. Sample A did not dissolve in water, but dissolved in aq. HCl. III. Sample N did not dissolve in water, but dissolved in aq. NaOH. Further testing confirmed that it is insoluble in aq. NaHCO3. IV. Sample Y dissolved in water and produced litmus paper results: Red → Blue; Blue → Blue V. Sample U is insoluble in H2O, aq. NaOH, aq. HCl and concentrated H2SO4. What is the most probable identity of sample G? What is the most probable identity of sample A? What is the most probable identity of sample N? What is the most probable identity of sample Y? What is the most probable identity of sample U?
