Phenylephrine, an organic substance with molecular formula C9H13NO2, is used as a nasal decongenstant in over-thecounter medications. The molecular structure of phenylephrine is shown below using the usual shortcut organic structure. (c) Would you expect a solution of phenylephrine hydrochloride to be acidic, neutral, or basic?

Hey everyone, we're told that ibuprofen is a non steroidal anti inflammatory drug. Its molecular formula is C 13 H 18 02 with a molecular structure shown below is a solution of ibuprofen, acidic neutral or basic. Looking at our structure below, we can go ahead and draw out our conjugate base. Now, when we draw out our conjugate base, we actually find that it is resonance stabilized and because it is resonant stabilized, this means that the formation of the car box lay ion is favored. So our solution of ibuprofen must be acidic, which is going to be our final answer. Now, I hope that made sense and let us know if you have any questions.
