Penicilin molecule

    1. The problem statement, all variables and given/known data


    From the structure of penicillin above, would you expect it to be acidic, neutral or basic? Explain your answer as fully as you can.

    2. Relevant equations

    3. The attempt at a solution

    I think it would be acidic because of the -COOH. The -NH- can be basic, but it is attached to =C=O which is deactivating. the electron density on the N atom is reduced and the tendency to accept a proton decreases.

    The other Nitrogen atom is also bonded to a deactivating =C=O.

    Is this reasoning ok?
