21. Picric acid (2,4,6-trinitrophenol) is slightly soluble in water but is readily soluble (with stirring and shaking) in both 0.6 M NaHCO3 and 2.5 M NaOH. Conversely, o-ethylphenol is insoluble in both water and 0.6 M NaHCO3, but soluble in 2.5 M NaOH. Explain. 22. Write an equation that accounts for the solubility of benzoic acid in aqueous base. 23. What would you expect to happen if a solution of sodium benzoate were acidified? Write an equation. 24. What would...

19. The over the counter analgesic aspirin is prepared from salicylic acid by a one step process as shown below. Would pure aspirin give a positive FeCl3 test? Justify your answer. OH OH -OH Salicylic acid Acetic anhydride Aspirin (acetylsalicylic acid) acetic acid 20. Caproic acid (molecular formula C.H20) is only slightly soluble in water but is readily soluble (with stirring or shaking) in both 0.6 M NaHCO, and 2.5 M NaOH. Conversely, formic acid is readily soluble in both...

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
