Homework Help: Penicilin molecule

  1. May 21, 2008 #1
    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.

    [b]2. Relevant equations[/b]

    [b]3. The attempt at a solution[/b]

    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?
